Doors not visible in 3D

[DangCad1]

I'm working on a project where the doors are not visible in 3D view or elevation, only the openings. 

They are visible in plan, and the doors are objects from the standard library (not "Empty openings" etc). 
What might be the problem here? See screenshots

   

 

Appreciate any help!

Check the > View > Elements in 3D View > Filter and Cut Elements in 3D... settings:

Thanks for your reply. Unfortunately, none of those seem to be the problem here. See screenshots below.

In you new screenshot there seem to be windows and door frames present, only the door leafs are missing. Is that correct? How does your Library Manager UI look like? Any warnings?

Check the Model View Options for the display level for doors and windows in 3D.

No, neither door frames or leafs for the interior walls, but the exterior door is fine (both door leaf and frame). If I eye-drop the exterior door (which is visible in 3D) to one of the interior doors, the dimensions of the door change but still no door frame or leaf.  So the problem seems to not be about the object, but something about the walls?

The Library manager looks like this, the only missing object is a zone stamp.

The MVO I have applied to the 3D view is "Drafting", for which the settings look like this. Can't find anything there that specifically applies to 3D views. However, since the exterior door is showing (Both leaf and frame), the MVO shouldn't be the problem here?

This MVO setting ...

I don't have that setting unfortunately (using Archicad 19)

As @Miha_M told you look into those missing doors in your Built-in Libraries as your screenshot tells us.
