Lets go through this step by step

1. By room, I am referring to the Rooms in the level editor -> when you right-click on the level name and do an Insert Room. If you haven't done this, all the physical rooms are in the same Room.
If this is the case, split them up into different rooms and set the Room Properties appropriately.
2. If you have already set them up as separate rooms, have you defined the Room Properties correctly (this is done in the Level Editor - check the image
here for the Room Properties button icon)?
Ignore my comment about the door, I was thinking of the doorframe. If all the above works, try doing that.
I can run a test when I get home in the evening.
