Door Error "can't make a type"

[Anonymous]

Hi, everyone!

I am new to the forum and Revit! I've got a problem with 3D image of the door. While placing door to the model there is an error "can't make a type" but revit creates the door with a bug. There is some sort of the shadow on 3D image (look at the photo).
I think there problem with nested family.
I placed here revit model with the door.

Thanks for help in advance

Set Opening cut to show transparent in 3D in the family.
