Manual Event Registration problems
just wondering - you are saying Profiles - are you absolutely certain you aren't referring to a 'group of custom fields'. This would make sense if you have added lots of groups of custom fields and set them to apply for 'all' events. they would then show for a back end registration.

If so there are two steps to consider

a/ do not make custom fields 'required' - only set them to required in the profile

b/ set the 'group of custom fields' so they only apply to certain Event Types
