I had a similar situation happen to me earlier this week. I added the Fullname from the Entity table to an existing table, in my case it was the TeamMembers table. When I added the field to the screen and went to Step 4 of 6, like Ashur has pictured above the only option available was REP via Entity. There are already 5 existing drop downs from the Entity table so I checked those and they were also only giving the option of REP via Entity.
Eventually I checked the conflicts and there was one conflict of trying to add a new customer with the same name as an existing customer. Once I delete the conflict I went back in and it worked correctly. It almost as though the drop down is saying even though this Fullname field is supposed to be unique, it's not at the moment, so I'm not going to make it available.
Ashur, can you try creating a conflict by adding a duplicate customer and then go in and edit the drop down and see if you then get wierd behavior on Step 4?
