Add custom font to visual composer issue - wordpress

Question

I have built a custom class that adds a custom font library to visual composer, and it works except that the icon selector always showing even if i change the library, as you can see in this image
, on the top there is the icon selector of flat icon library while i have selected the fontawesome library.
Note: Fontawesome's icon selector also showing in the same time
Here is the class:
<?php
if (!class_exists('Fama_VC_Fonts')) {
class Fama_VC_Fonts{
/**
* #var string
*/
public $font_library;
/**
* #var array

/**

*/
public $fonts_lib_meta;
/**
* Class constructor
* #param array $library_data Font library data
* #return void
*/
public function __construct($library_data){
//check if visual composer is active
if(!fama_is_active_plugin('js_composer/js_composer.php')) return;
if (!is_array($library_data)) return;
if(empty($library_data['font_library']) || empty($library_data['fonts_list'])) return;
$this->font_library = $library_data['font_library'];
$this->fonts_list = $library_data['fonts_list'];
$this->fonts_lib_meta = $library_data['fonts_lib_meta'];
// In the 'Icon library' dropdown for an icon content type, add a new family of icons.
add_filter( 'vc_after_init', array($this, 'add_vc_icon_library'), 40 );

Answer 1

I have figured out where the problem is. It is this line:
'element' => 'icon_type',
Which should be:
'element' => 'type',
Now only selected library is showing.
