Double door issues

[craggy jungle]

So I'm trying to make a double door but I just can't get it to work. I used a copy of the original fbx meshes but reapplying the meshes for some reason makes them not show up. If I replace the meshes with regular meshes they do show up, but missaligned and of course they don't have proper armature. How do I fix this?

in blender it works perfectly fine

Unfortunately your Blender hierarchy is covered by the GeForce Experience capture notification.
