Why are relative coordinates from a BP transformed into world coordinates for static mashes?

I’m trying to add some physics constraints (like ropes) to a rag-doll and for that I’m using some static meshes (spheres). The problem is that even if I set the coordinates (transforms) to relative in BP Editor, when I drag the BP into the Main Editor coordinates are transformed to world coordinates no matter what I do.

Is this a BUG or am I missing something?
