You are saying that in edit mode, the name of the person in the profile AND in [ ] their Wiki ID# is displayed, and this has begun to occur recently ?
This is a phenom that is occurring on the profiles I manage, also.
It does no harm that I can think of, and is no doubt due to the massive number of tweaks recently implemented -- last week, I think, or the week before ... I don't think it is one of the many bugs that erupted when the tweaks were implemented
