Group name is not available

Attempting to create a group for a forum in which I’m a moderator running latest Tests-Pass. When I go to create a group I see Group name is not availabile even though no such group has been created. I’ve asked admins and they are not sure on what the problem is.

Group - Group Name is not available
Groupna - Group Name is available
Groupname - Group name is not available

It seems these names are all taken by users. Now it is just a process of asking them to kindly change their user names to something else, or we can anonymize their user account to free it up. All names I’ve checked have only 1 - 3 posts total.

You can reserve user names you don’t want used:
