Multiple exit areas

[BulletFingers]

I'm working on a level and don't actually want multiple exits, but think I have somehow added an extra exit that I can't get rid of, despite making a new exit by pressing '5' after shift selecting an area.
Does anyone know about this?

I figured it out incase anyone else has this problem -

The reason my exit wasn't working is because i was holding down shift while pressing 5. This creates a box outline that does nothing (as far as I can tell). Possibly to keep track of space?
Anyway if you press shift + 6,7,8, or 9 you can make different colored boxes.
It also looks like you can make different colored boxes without pressing shift that also do nothing.

Overall, the only way to make an exit is Shift highlight, let go of shift, press 5.

Edit: The other colors might be for different game modes now that I think about it. I was doing game type 0

The other color's are warp zones!
