Rigidbody wont bounce off other rigidbody, why?

I have 2 rigidbodies each setup with a collider and the default bouncy material

When the first rigidbody hits the second one it goes to a full stop.

Is that normal behavior? Is there a way to have them bounce against each other instead?

FYI they are not set to kinematic. If I set one of them to kinematic it does bounce but then it creates a problem were the object is now able to get out of the playing field’s limits that are setup with colliders.

Thanks.

Maybe the mass is high on one and low on the other?
