An extra user on the list of moderators

Question

On the list of moderators, one of the users is not like others. He is a former SE employee, not a moderator.

Answer 1

This is an artifact of the status of his accounts being changed from employee to normal user since he recently left SE.

Its been noted that this has happened on a few sites, I'm sure it will get resolved in due course.
