Remove (Or) Empty Duplicate OpenGraph Induced By Unknown Plugin/Theme - wordpress

I am trying to use Yoast SEO fully. But my theme or some unknown plugins are introducing another opengraph tag section overwriting Yoast's metadata. How do I eliminate the second duplicate set?
Here is the list of plugins that are currently installed - Akismet Anti-Spam, AP Theme Utility Plugin, Featured Image from URL, Jetpack by WordPress.com, Page Builder by SiteOrigin, Proxy Cache Purge, Random Banners, Social Share WordPress Plugin - AccessPress Social Share (Tester), VaultPress, WP Extended Search, WP Responsive Recent Post Slider,Yoast SEO. The Social Share plugin is to show share buttons underneath each post and I did disable it to yield nothing in change of my metadata.
I have added this code my theme's functions.php file - add_filter( 'jetpack_enable_open_graph', '__return_false' ); which is a strong confirmation that Jetpack's open graph tags are disabled all across the site.

Here is Yoast's metadata

Here is another metadata set generated after this section and some other data
<meta property="og:title" content="Chaganti Pravachanam On Venkateswara Vaibhavam In Nagpur" />
<meta property="og:description" content="Chaganti Pravachanam On Venkateswara Vaibhavam In Nagpur">

<meta name="twitter:image" content="https://i.imgur.com/1TDYQNc.jpg" />
If you observe closely, you can see that the og:image of Yoast SEO is different from that of the theme/unknown plugin/jetpack generated one in the second set. This is because Yoast only generates og:image tag when there is an image in the post content. And when there is just plain text even with featured image set, it doesn't put one. More info in this issue here - https://github.com/Yoast/wordpress-seo/issues/12794
Now all I want is to add some sort of a code into my functions.php file to make the second set of metadata go away except for og:image tag. Here is the expected result
<meta property="og:image" content="https://i.imgur.com/1TDYQNc.jpg" />
This way I can make sure that my Yoast SEO's metadata is retained and the og:image tag issue is also fixed.
I spoke to the theme developer and they mention that other than the title tag and description tag, their theme is not generating any opengraph tags as the one in the second set. I highly doubt Jetpack and any ideas are most welcome. Thank you.

Open Graph Meta Tags are marked as Invalid

My site is a WordPress site, version 5.02
[http://www.baddog3d.com][1]
I cannot determine why the debugger keeps tagging the meta tag: og;url as invalid. I have tried with "http://" and "https://" and headless but still receive the same error.
These are my meta tags that the Yoast plugin creates for the head section

Facebook sharer showing (almost) always the wrong author

I can't understand why Facebook sharer keeps showing the wrong article's author when sharing articles of my website. (Of course I always use Facebook Debugger before sharing).
Take this article as an example: although it is clearly written by Francesca Aloisio, it keeps showing (when shared) "by Virginia Vigliar".
Facebook Debugger reports:
<meta property="article:publisher" content="https://www.facebook.com/wordsinthebucket" />
<meta property="article:author" content="https://www.facebook.com/francesca.aloisio.397" />
I just can't figure out why.
N.B. I use Wordpress SEO by Yoast.
Why are you having the og values defined twice?
Have a look at below (line 23 to line 47):
<!--Facebook Open Graph-->
<!--FB page title-->
<meta property="og:title" content="Indonesia Makes a Sharp U-turn on Virginity Tests" />
<!--FB description-->
<meta property="og:description" content="Most students in the world may think that in order to get their high school diploma they would have to meet certain requirements: good grades, good attitude towards school, good relationship with teac..."/>
<!--FB url-->
<meta property="og:url" content="http://wordsinthebucket.com/u-turn-indonesia-virginity-tests"/>
<!--FB image-->
<meta property="og:image" content="http://wordsinthebucket.com/wp-content/uploads/2015/02/indonesia-exam.jpg" />
<!--FB type-->
<meta property="og:type" content="article"/>
<!--FB site name-->
<meta property="og:site_name" content="Words in the Bucket"/>
<!-- This site is optimized with the Yoast SEO plugin v2.3.5 - https://yoast.com/wordpress/plugins/seo/ -->
<title>Indonesia Makes a Sharp U-turn on Virginity Tests</title>

<link rel="canonical" href="http://wordsinthebucket.com/u-turn-indonesia-virginity-tests" />
<link rel="publisher" href="https://plus.google.com/+WiBTeam/about"/>
<meta property="og:locale" content="en_US" />
<meta property="og:type" content="article" />
<meta property="og:title" content="Indonesia Makes a Sharp U-turn on Virginity Tests" />
<meta property="og:description" content="Indonesian officials were forced to take a step back on their proposal of introducing virginity tests for high schoolgirls." />
<meta property="og:url" content="http://wordsinthebucket.com/u-turn-indonesia-virginity-tests" />
<meta property="og:site_name" content="Words in the Bucket" />
Remove either one of them, because this is causing the FB Debugger to show that:
Try adding
<meta name="author" content="[THE_AUTHOR_HERE]">
also plus removing the duplication and then going here: https://developers.facebook.com/tools/debug/og/object/ insert the url and press "fetch new scrape information" and see if that fixes it.
First of all: thank you all for your replies. However in the meanwhile I changed my theme cause I realized that it was an issue related to my previous one: it had a "top post" part at the very beginning of the page and the first post showed in there was seen by the FB sharer as the meta "source".
Regarding the double og values, thank for noticing. My actual theme appearently has its own "SEO". So I just removed it from the header.php file and keep YOAST SEO doing the job.

og:site_name ignored for facebook comments plugin?

I'm using Facebook's comment plugin, and I have point to a page with open graph tags set up.
When a user makes a comment on my page using the plugin, all of the og tags are used by facebook in the wall post, except og:site_name, which should go in the caption of the link but instead the domain of my site is appearing.
example HTML:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#"
xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>My Title</title>
<meta property="og:type" content="article" />
<meta property="og:site_name" content="My Site Name" />
<meta property="og:title" content="My Title" />
<meta property="og:url" content="http://www.example.com" />
<meta property="og:image" content="http://www.example.com/some_image.png" />
<meta property="og:description" content="This is a description" />
<meta property="fb:app_id" content="FB_APP_ID" />
</head>
<body>
.....
</body>
</html>
But here's what I end up seeing on Facebook:
example
Note the caption says "www.example.com" instead of "My Site Name" which I expected to see there.
Anyone know why OG would be ignoring my tag?
Thanks in advance,
DW
Not a fix but a possible reason.
There's an opened issue in the Facebook Bug DB:
Incorrect site name appearing in shared links on Facebook
Unfortunately, it seems to be a low priority issue.

Facebook Like Button Text in feed?

With the facebook iframe like button, am I able to specify what text shows up in a users stream?
When I use a plugin for a wordpress blog post it shows up at
USERNAMe likes POST TITLE on BLOG NAME
but when I try and put it on another page with the straight up iframe code, i just get:
USERNAME likes http://www.pagename.com/bla/bla/bla
How can I specify what text shows up?
Do you have open graph tags on your page, like:
<html xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<meta property="og:image" content="..." />
<meta property="og:site_name" content="..." />
<meta property="og:title" content="..." />
<meta property="og:url" content="..." />
<meta property="og:description" content="..." />
<meta property="og:type" content="article" />
</head>
