You are not dividing the room in a way that will create a new room within leaving space.
Try doing zones. Its much easier then modifying room on the map. Pretty sure there is a bug, which is making things tougher than it should be.
I had the same issue and thought merging all rooms would help. Nope, I was still getting the error just trying to split kitchen from living room. It finally let me, but I had to divide half my 1st floor. After doing that, I had to do combinations of divide and merge to get the map correct. When all said and done, took about 60 minutes for a few rooms.
Hello, thanks for reaching out. Could you pls send us a screenshot to show the house floor plan and where you'd like to divide the room?
