Group admin details are editable. If as superuser I change the email address for the group admin, what happens is rather than updating the email, it creates a new group admin account, leaving the current account as well. It should instead update the current group admin email address. (I'm assuming the email address is being used as the identifier, hence the problem.)
Low priority as it's only seen by the superuser, and is unlikely to cause problems.
