Is there anything unique about how you have the Make table setup? I looked at a handful or different forms with the new setup, but 1) I don't see anyway to control this and 2) I don't get the behavior as you've described it. When I click Create in the dropdown it opens the popup and on save populates the field with the new value similar to the behavior of the old forms.
I started with a template from the QB library so it's possible there is something unique that is buried somewhere. Interesting that you don't get the same behavior; I'll start with a blank slate and run a test to see if the behavior changes.
Odd. I would suggest just making a new form then as you've suggested and try just putting that field on there alone and seeing what the behavior might be.
OK I figured it out. The Make (parent) was still a legacy form but the Model (child) was using the new forms builder. Once I made a forms builder form for the Make table, I get the behavior I want.
