TYPO3 Mask CE background image - css

Question

I'm trying to get a background image or color in a CE element in Mask extension.
This is what I get as out-put but no image and no background color?
What Am I missing forgetting here? Seems all OK to me :)
<div id="c71" class="csc-default">
<section class="test_one" style="background-image: url('fileadmin/_processed_/c/6/csm_pizza_uit_de_kleine_pizzajolly_pizzaoven_campegio_eb7fa491f7.jpg') no-repeat center center; background-size: cover;">
<div class="row wrap">
<div class="large-12 small-12 columns">content</div>
</div>
</section>
</div>
</section>
this is in my template:
<f:if condition="{data.tx_mask_achtergrond_afbeelding}">
<f:then>
<f:for each="{data.tx_mask_achtergrond_afbeelding}" as="file">
<section class="<f:if condition="{data.tx_mask_class_name}">{data.tx_mask_class_name}</f:if>"
style="background-image: url('{f:uri.image(src: file.uid, treatIdAsReference: 1)}') no-repeat center center; {data.tx_mask_kleur_actergrond}; background-size: cover;">
<!-- if content CE than: -->
<div class="row wrap">
<div class="large-12 small-12 columns"><!-- content element here: text / button -->content</div>
</div>
</section>
</f:for>
</f:then>
<!-- if no background image than background-color and content CE-->
<f:else>
<section class="class-name"
style=background-color:"<f:if condition="{data.tx_mask_kleur_actergrond}">
{data.tx_mask_kleur_actergrond}
</f:if>
;">
<!-- if content CE than: -->
<div class="row wrap">
<div class="large-12 small-12 columns"><!-- content element here: text / button --></div>
</div>
</section>
</f:else>
</f:if>

<section class="test_one"
style="background-image: url('fileadmin/_processed_/c/6/csm_pizza_uit_de_kleine_pizzajolly_pizzaoven_campegio_eb7fa491f7.jpg')
no-repeat
center
center;
background-size: cover;">
do you want only set the background image or do you want to set also the formating and positioning of the background image?
You start with background-image: but set all paramters as for background:
