Hi Tuan,
when in frontend "Registration History" I hit the link to edit "Member 2" of a Group registration, I expect to visualize in the edit screen just the fields I set for "Member 2" (as in registration process) and not all the fields set for "Member 1". By the way the real problem is that I'm forced to fill all the required fields that I don't wont and need.
I think that some setting (see attachment) is wrong or not working as espected.
I tested all the "Display In" properties without success.
Thank you
Luca
