Custom Post Types + Advanced Layout Builder + Block Editor

Hey guys– I am diving into the Custom Post Type code as I have this current project and a couple upcoming client projects that will lean heavily on this.

I installed the CPT UI Plugin and Registered ‘Regions’.

I added this code snippet to my Child Theme Functions.php file:

// Add Advanced Layout Builder to Custom Post Types

function avf_alb_supported_post_types_mod( array $supported_post_types )
{
  $supported_post_types[] = 'REGIONS';
  return $supported_post_types;
}
add_filter('avf_alb_supported_post_types', 'avf_alb_supported_post_types_mod', 10, 1);

Things look good initially… CPT Regions shows in the Admin Panel. I create a new post, and the ALB Editor is showing up…
However… the G. Block Editor is above it. Only content added in the Block Editor is rendering in the post, and content rendering in the ALB section s below are not.

The normal behavior for Posts, Pages, Portfolio is to have an ALB button at the top which disables the Block Editor, but that isn’t happening either (I;’m assuming this is the root of the problem).

What am I missing?
