I can't teleport (VR) if my meshes are children of an Actor (?)

Hey all, I am facing a very annoying issue:
I imported my meshes as USD file, it has imported everything correctly, instances, etc. I’m happy with it, textured everything, set up light but now that I’m trying to start playing around with VR, even though my meshes are all correctly set with collisions and the navmesh is also set I can’t teleport anywhere but the “root” Actors position which is parent of all the meshes in my project.
If I manually bring the meshes from the folder USD created to the level, then it works perfectly.
I couldn’t find a way to “explode” this group, or ungroup, or anything! I can copy, paste, duplicate, delete, everything as long as it is inside the Actor Root. Is there a way to fix it?

Thanks,
