Why hinge joint rotates arounf collider center not around anchor

Hi,

I am confused by a strange behaviour with hinge joint and colliders (Unity 2021.3):

That is working as expected, the hinge joint has defaults values except limits and uses vertical box as connected body, rigidbodies are set to use gravity and constraints as descripbed in image below, rest is default values:

But now, when I add a box collider to the box with hinge joint, it does not rotate around the anchor point anymore , but around the box collider center.

Why does the box not rotate around anchor point anymore??

Thank you.
