Layout builder not working when logged in under custom WP role and capabilities

I have written a custom post type, added the Avia layout builder to the CPT, and defined custom roles/capabilities for the CPT.

However, my custom roles will not allow me to fully use the layout builder. It will load and I can add elements, but when I save they are all removed and then I try to load a template I get an error that says I am not longer logged in, but I am and everything else works just fine.

I looked over the capabilities and I do not see ant look like the are related to the theme. Any ideas?

When I am logged in as Admin, the layout builder works fine, just not under the custom roles.
