I am trying to create or edit a new page, custom page, custom post type. I expect to see the edit screen. Instead I see the the Edit Layout screen for the corresponding associated layout. For example, if I try to publish a custom post type called "Blog Post", the system creates and loads a "Layout for Posts" layout. If I try to publish a regular WordPress page, the system creates and loads a "Layout for Pages" layout. I can't get to the regular edit screen.
The system keeps generating new versions (see attached). If I try to delete any of these, it loads a broken view of the layouts page (see attached).
