Prune/Move Users, Moderator
 

I noticed while checking through the prune/move users option, that some members are listed as moderator, and therefore not editable under the prune/move users option because of the ! button. The members were moderators before but I removed their status. I have double checked they are not moderators on any individual forums, and not in the moderator usergroup or additional usergroup, and I have pruned all traces of their logs from the moderator logs, yet they are still listed as moderator.

Does anyone know why this is and how I can remove that status from their usernames?
