"In addition, if I try to use the same email address in a group registration for each group member (often done in my client's use case), it prevents me from using it, saying: "Invalid field: Email". The user (registrant) is NOT logged in." . You have setting in DTregister config "general Tab" "Duplicate Registration Prevention:" Yes . So any duplicate email user/member not allowed .
Issues related interface UI/UX had reported to team . Will look into it .
