So I designed a 2-story plan with a basement (on the foundation level).  I got the basement floor plan, 1st floor, 2nd floor and roof completed.  Then started working on detailing the inside of the house, adding cabinets, doors and windows.  I started on the 2nd floor and everything was fine.  When I went to the 1st floor and would add cabinets, doors, windows they would end up in the basement like there's no floor between the basement and 1st floor.  I can drag them up in 3D views to make it look sorta right but cannot figure out what went wrong or how to fix it.  Attaching a screenshot of what it looks like.  I have dragged the cabinets and windows up.  Also attaching the full plan file.
