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.
Interesting. Good to know!
