There is a ceiling in 3D visit mode when there shouldn't be

[Edenwolf]

Ok so I have level 0 and level 1 so far. Assuming level 1 is the second floor, I have made two 10'x 10' floors that are going to be lofts and the rest of level 1 is empty space. When I go into 3D visit mode when I'm set to level 0(main floor) and I look up I should see the roof peak and underneath the two lofts but instead all I see is a ceiling running the entire house(that would be the floor to the second level.
