Massive CSS issues – classes not editable cause gone

There are massive issues with your theme – probably update related.

Here what`s going on – explained on one single example – but there are more:
In page XY there should be a CSS class: <em>headerinoverlay</em>
The class is <strong>still in the database</strong>, in the table <strong>postmeta</strong>

[av_image src='https://......./wp-content/uploads/portrait.jpg' attachment='30256' attachment_size='full' copyright='' caption='yes' styling='' align='center' font_size='14' overlay_opacity='0.2' 
overlay_color='#000000' overlay_text_color='#ffffff' animation='fade-in' hover='av-hover-grow' appearance='' link='lightbox' target='' title_attr='' alt_attr='' lazy_loading='enabled' id='' custom_class='' template_class='' 
av_element_hidden_in_editor='0' av_uid='av-6j99wqx' sc_version='1.0' admin_preview_bg='']
<span class="headerinoverlay">TEXT
[/av_image]

The class <strong>is NOT in the actual HTML</strong> sourcecode.

<div  class='avia-image-container av-6j99wqx-4360db518504a459e880005aec5fa2b1 av-styling- av-hover-grow avia_animated_image av-animated-when-visible-95 fade-in avia-align-center  avia-builder-el-3  avia-builder-el-no-sibling  noHover av-overlay-on-hover'   itemprop="image" itemscope="itemscope" itemtype="https://schema.org/ImageObject" ><div class="avia-image-container-inner"><div class="avia-image-overlay-wrap"><a href="https://www………./wp-content/uploads/portrait.jpg" data-srcset="https://www………./wp-content/uploads/portrait.jpg 800w, https://www……./wp-content/uploads/portrait-80x73.jpg 80w, https://www......../wp-content/uploads/portrait-768x697.jpg 768w, https://www......../wp-content/uploads/portrait-705x640.jpg 705w" data-sizes="(max-width: 800px) 100vw, 800px" class='avia_image' ><div class="av-image-caption-overlay"><div class="av-caption-image-overlay-bg"></div><div class="av-image-caption-overlay-position"><div class="av-image-caption-overlay-center"><p>TEXT</p>

The class<strong> is NOT in the ALB</strong>

[av_image src='https://......./wp-content/uploads/portrait.jpg' attachment='30256' attachment_size='full' copyright='' caption='yes' styling='' align='center' font_size='' overlay_opacity='0.2'
overlay_color='#000000' overlay_text_color='#ffffff' animation='fade-in' hover='av-hover-grow' appearance='on-hover' link='lightbox' target='' title_attr='' alt_attr='' lazy_loading='enabled' id='' custom_class='' template_class=''
av_element_hidden_in_editor='0' av_uid='av-6j99wqx' sc_version='1.0' admin_preview_bg='']
TEXT[/av_image]

So there is no way to edit it or remove it cause i cant find.
When you compare the code from the database with the code from the ALB you will realize that there are also other things wich are different.

This (gone CSS) happened to a lot of CSS and this is a very serious problem.
Please fix it or tell me how i get my CSS back from the DB into the ALB!
