Membership Plugin Invite Code Problem

If BuddyPress has any customer user profile fields that show up on a Membership registration page then the Invite Code box is repeated once for every custom profile field.

See this screenshot as an example:

Is this a bug in Membership? Can it be fixed to only display the invite code registration field the one time?

Thank you!
