Is this affecting all of your users in that group, or just a single one?
What happens when you remove the user from that group and then re-add them?
Both the "Group Editor" and "Edit Profile" pull their data from the exact same ubbt_GROUPS and ubbt_USER_GROUPS tables. Something must be different with this single user, which is not affecting the other users which you say are in exactly the same groups, and are able to choose a Group Image.
