CPT UI posts not showing

Aloha, you may have to use a custom template to render post meta fields from your custom post type. See: https://medium.com/@wesmodes/using-wordpress-insert-pages-plugin-with-your-custom-post-types-and-custom-templates-535c141f9635

If that doesn’t apply, please provide more details about what you are seeing with CPT UI. Cheers
