Can't place rooms in temple

I'm in campaign and got to the point that i can't place any rooms and run the temple, none of the available rooms "fit" to the ones i earlier placed so i'm kinda stuck.

Got it , learned how to read all of a sudden, problem is no more.

What was your fix that you read? I am also stuck and cannot place any rooms so I don't know how to start the temple

Update: I found somewhere else that you can control+click to bypass the place room restriction in case anyone else stumbles on this thread.
