creating open air courtyard in cent of the house

[Syngyn]

I have a design that has two courtyards inside the mail exterior walls. One of the courtyards drew just fine, with the external wall siding facing the to the inside of the polygon. The other, however, wants to face the external wall to the interior part of the house. I have clicked on all of the walls, selected flip layers to change them. When I go to save the files, the system changes them back. Also cannot make the program understand there should be no ceiling or roof above the courtyards.
