This might be tricky to explain, but if you don't have all of the rooms on the Cinema tab, it might make sense.

Earlier, I noticed that when I moused over the Western room, which I don't have, the area behind the room did not light up; instead, the area that lit up was the behind the Shooting room.

I do have the Shooting room, but the area in front of and behind the room is not lit up; that only seems to happen when mousing over the Western room.

I checked another doll who had the Western room, but not the Shooting room, and it was the same thing.
