CPTs and Taxonomy register issues

Hi, This is a follow up to a previous ticket:#22643 that somehow got "Resolved". I'm still having issues.

I created a new CPT and Taxonomy and the “[object Object]” has not shown up in the PHP code.

When I created a new CPT with v2.0.4, the “Supports” display Tab is blank. The default ‘supports’ = [‘title’, ‘editor’, ‘thumbnail’] shows, but I have no way to modify it.

Two questions:

When creating a taxonomy, do i have to add the taxonomy to the CPT AND add the CPT to the taxonomy?

Also, how do I fix the current CPTs and Taxonomies. The CPTs still display “[object Object]”?

I installed the “Query Monitor” plugin and it’s showing the following Warnings and Notices for the MB Custom Post Type plugin. See attached.

Thanks.
