When people say 'room markers' are they referring to Roombound/Portal? Just curious since I have never dealt with anything called a Roommaker. (might clear things up for him) If it's the Roombound as far as I know it can be hidden, and usually doesn't cause me any problems, but if there are room markers, further explanation would enlighten me on it also. I rarely edit existing cells and when I have, I haven't noticed any issues like the above.
