Hello, This is my first time posting a question on the forum so be gentle, thanks. I have a plan for a new house here it has a basement and 2 floors above. The strange thing is that the basement and the first floor are situated on a white rectangle surrounded by a blue grid. The second floor is situated directly above the first floor but it is not inside the white rectangle, in fact it's partly in the rectangle and partly in the strange blue grid. I did not create the white rectangles or the blue grid as far as I can tell. I have a screen shot attached. Please drop whatever you are doing and focus all your time and energy into this issue, thank you in advance.
