I’ve got a similar issue but with me I can see the content in the editor i.e. (/wp-admin) but it doesn’t show up on the actual site… This is the first container in a horizontal grid of 3 containers, the content is supposed to be a paragraph and a list. The 2nd and 3rd container’s content show up fine. Here’s an example of the html output that is generated:
<div class=”gb-grid-column gb-grid-column-9ca79350″><div class=”gb-container gb-container-9ca79350″><div class=”gb-inside-container”>
</div></div></div>
