SSE Disappearing internal doors problem

[DemonicTurkey]

I am creating a player house. Inside I have seven display areas for various trophies. The displays I am using are Darkfox127's displays with glass doors. Each display has a left and right door. When I view the displays in game there are always two doors missing. One left door, and one right door. The strange thing is that it's not always the same two doors that go missing. When I approach the missing doors I still get the prompt to open, and when I use it I hear the opening sound, but do not have access to the trophies inside, as the door's collision barrier seems to not have moved. Even stranger is the fact that when I leave the cell, the load door opens slightly, and I can see the the two glass display doors are sitting on top of the same spot as the front door. The other glass displays all work perfectly.

 

Any insight into this problem before I lose my mind is appreciated.
