Strange #after_section block added to every page

Hey there –
I’ve got Enfold on at least a half dozen other sites and have never seen this. But it is happening on every page now.

After the last Color Section there is a mysterious 100px tall (which I now is the min height for content sections) section. I can remove it by targeting it with CSS, but that seems like a hack to me.

Below is the code.

<div id="after_section_4" class="main_color av_default_container_wrap container_wrap fullsize"><div class="container"><div class="template-page content  av-content-full alpha units"><div class="post-entry post-entry-type-page post-entry-81"><div class="entry-content-wrapper clearfix">
</div></div></div><!-- close content main div --></div></div>

I added a link to a page on our staging site for you to look at.

Any thoughts on why and how to get rid of it?
Thanks,
Kane
