Bug with doors (House Flipper)

In the winter cottage "Snow is Falling" after the sale of doors with broken glass, I can not put new ones, writes that there is not enough space for them, although the doors fit perfectly in the opening. If you put doors 2 by 2 meters, then it does not allow you to build upper walls and, in general, does not allow you to put up walls. Is it possible to somehow fix this?
