When I was changing the joint value of the UR10 arm in the Isaac Sim, I found the ur10 arm can go through itself. Is there anything I need to set for it? Or it is just a bug.

Click on the main ur10 prim and check the enableSelfCollisions box
Then press play to start simulation. Did a quick test in the screenshot below
