WordPress Updates PageBuilder

Hey guys,
if you help me I would be really happy 😀

My problem is that in WordPress 4.4.2 all entries from PageBuilder-Plugin are surrounded by 2 div classes.. The first “developer” of the Website used them to get everything on max-width: 1320px and auto-margin. (custom theme ..)

<div id="pl-4"><div class="panel-grid" id="pg-4-0" ><div style="background-color:#f1f3f5;" class="panel-row-style" ><strong><div class="columns-wrapper"><div class="columns"></strong><div class="panel-grid-cell" id="pgc-4-0-0" ><div class="so-panel widget widget_sow-editor panel-first-child panel-last-child" id="panel-4-0-0-0"><div class="so-widget-sow-editor so-widget-sow-editor-base"><h3 class="widget-title">Headline</h3>
<div class="siteorigin-widget-tinymce textwidget">
	<p>Text</p>
</div>
</div></div></div>

I updated to 4.5.1 now and it looks like this:

<div id="pl-4"><div class="panel-grid" id="pg-4-0" ><div style="background-color:#ffffff;" class="panel-row-style" ><div class="panel-grid-cell" id="pgc-4-0-0" ><div class="so-panel widget widget_sow-editor panel-first-child panel-last-child" id="panel-4-0-0-0" data-index="0"><div class="so-widget-sow-editor so-widget-sow-editor-base"><h3 class="widget-title">Headline</h3>
<div class="siteorigin-widget-tinymce textwidget">
<p>Text</p>
</div>
</div></div></div>

I know it’s a little less to get something with but if someone got an idea how to get the 2 div classes again i would love him.

I just updated WordPress and not the plugin or theme itself. So in my opinion it is a change in the WordPress files that the 2 classes are not there.

Thanks if you can help.
