It was OK even with the fourth table until I changed the entity name of the entity for which the fourth table was created. When I roll back to a version with the fourth entity but before I renamed it, everything seems to work so I am guessing that is what broke it.
I didn’t understand this part. It’s not clear what was working and what is not, and what exactly do you mean by rolling back.
The only way to understand this issue is if you replicate it with this test case template. We can analyze the test case afterward and tell you what’s wrong with it.
