Importing one .FBX file with multiple meshes - UVW's are gone

Importing one .FBX file with multiple meshes - UVW’s are gone

When I import an .fbx file, that contains multiple meshes.
The UVW Information is gone.

Why?
How to avoid that?

When I check the same .fbx file in any other software package, like Blender, Max, Maya or C4D. The UVW’s are still there.

Is this a bug?
