[Map Bug] Wardens Quarders have wrong name

The map "Wardens Quarders" is also named "Upper Prison".
If i'm in the Upper Prison map and mouse over the exit to the next area its called "Wardens Quarders".

So there are two "Upper Prison" now.

I get this too if I make portal in the Warden's Quarters, leave, then return. The lighting is no longer reddish, the music is that of the other two prison levels, and the map is now called "Upper Prison" on the top right hand indicator.

If I leave to the real Upper Prison and return, the issue is resolved. If I then portal in and out again, the same problem occurs.

Everything else seems to work fine enough in the level; I can kill Brutus and leave. The mysterious person triggers properly too.
