Grid row layout element generates after_submenu elements with nested containers

Hi,
thanks for your reply.
I have updated the page so the issue is clearer, on the page I now have:
– 1/1 element
– Grid element
– 1/1 element
As you can see the last 1/1 element is indented, which should not happen. I have inspected the last 1/1 element and the html is as follows:

<div id="after_submenu_1" class="main_color av_default_container_wrap container_wrap fullsize" style=" ">
<div class="container">
<div class="template-page content  av-content-full alpha units">
<div class="post-entry post-entry-type-page post-entry-4623">
<div class="entry-content-wrapper clearfix">

<div class="flex_column av_one_full  flex_column_div av-zero-column-padding first  avia-builder-el-12  el_after_av_layout_row  avia-builder-el-no-sibling  " style="border-radius:0px; ">
<section class="av_textblock_section " itemscope="itemscope" itemtype="https://schema.org/CreativeWork">
<div class="avia_textblock  " itemprop="text"><h2>This is a full width element 1/1 but it is nested in a new ‘contaner’ div for some reason</h2>
</div></section></div>

</div></div></div></div></div>

The first 5 divs are totally redundant because all elements are already in a wrapper and a container, so these are not necessary. In fact, if I remove them with Inspector and only leave the following then the layout works as intended.

<div class="flex_column av_one_full  flex_column_div av-zero-column-padding first  avia-builder-el-12  el_after_av_layout_row  avia-builder-el-no-sibling  " style="border-radius:0px; ">
<section class="av_textblock_section " itemscope="itemscope" itemtype="https://schema.org/CreativeWork">
<div class="avia_textblock  " itemprop="text"><h2>This is a full width element 1/1 but it is nested in a new ‘contaner’ div for some reason</h2>
</div></section></div>

I am not sure what is causing the Theme to add un-necessary HTML.

Let me know.

Thanks
