How can I make rigid_object not collide with others.

[WSYANGSX]

Hello!
When I use IsaacLab to build my own env, I found two rigid_objects can still collide with each other although I have set collision_props to False. I want to know how to make them not collide with each other.Thank you!

And I find some Warning on termination.

Same here under the same environment, it will collide with each other. I tried sim_utils.CollisionPropertiesCfg(collision_enabled=False), got the same warning and object still collide with each other
