Hello,
When importing an .ifc File into FreeCAD only some windows and doors are visible in 3D, even though all of these components can be found in the ifc manager with the correct ifc classification.

When selecting an individual door or window, it seems that the objects exist multiple times in the exact same location. I am using .ifc2x3 but get the same result with .ifc4. When importing the exact same file in Revit, all windows and doors are visible.
