In the Model View Option settings, check the Level Of Detail for the doors and windows.
It may be set to 'Simplified' rather than 'Full'.
I am fairly sure that may be the solution for your doors and windows.
There is a similar setting in the MVO for railing options - although I am less sure if that is the problem there.
