Mesh doesn't follow collider while simulate physics asset

Here’s a video about the issue:

I’m making a car door constraint in the same way you would make it on a character skeletal mesh: the door bone is child of the chassis bone and it has a single convex hull shape attached so ue4 automatically created the constraint for me. The fact is that, when i simulate, the collider of the door separate from the mesh and act on its own. Also, i can’t abjust the orientation of the constraint limits simply orienting the constraint itself (method i read on the web) but it always manteins the default orientation, making my car door swing half inside the car and half outside (not showing in the video).

Can anyone help me? Ready to bring more info on this if needed
