"Only require for first group member" Not Working?

For the First Name and Last Name fields I have "Only require for first group member" set to Yes. In group registration, "Member 1" correctly requires those fields, "Member 2" correctly removed the validate[required] and is not required; however, for Member 3 and above it's saying that the First Name and Last Name fields are required, and in the code I still see "validate[required]" assigned to those fields for Member 3 and above.

Is anyone else experiencing the same issue, if the First Name and Last Name's "Only require for first group member" is set to Yes it's not required for Member 2, but is still required for Members 3 and above?

Thanks!

Look like a bug . A quick fix would be opening the field administrator/components/com_eventbooking/libraries\rad\form/field.php, find the method makeFieldOptional and remove this code:

I will check it carefully for a proper fix later (today or on tomorrow)

I also need this option to work, I WANT a field that is not showing up (both First Name and Last Name in all the group members registrations) no matter how I set the option.

Thanks!
