Description

When I try to use the Post Content block, it tries to add another post content and says I can't do one inside another. I have not used this module before, first time trying to use it to set up a layout template for single blog post template using Reusable Block Extended for a shortcode. I've tried editing on a post or post, same issue occurs.

Step-by-step reproduction instructions

I go to edit a post or page, add Post Content to the page, I get this error shown in screenshot. I have tried it on another site, same error/issue happening.
