IsaacLab RL training with mimic joint robot asset

Hi everyone,
Im training a policy for a robotic arm using the IsacLab framework.
The arm gripper is modeled with some mimic joints inorder to get the right paralleled motion of the gripper’s tips.
While loading the scene some Physx errors regarding the replication of the mimic joints are raise (see attached image). Other than that it seems like the behavior of the joints on all environmets are as expected so I wonder what is the meaning of those errors?
Tnx,
Nitsan
