PBIK warning, trying to apply Bone Settings to bone?

I am trying to make my metahuman ragdoll, but it keeps flooding me with this warning and wouldn’t simulate. I think it has something to do with the ik rig? but how do I simulate a bone between root and effector(whatever that means)? even google didn’t have any answer for me. can anyone help?

LogPBIKSolver: Warning: PBIK: trying to apply Bone Settings to bone, clavicle_l, that is not simulated (not between root and effector).
LogPBIKSolver: Warning: PBIK: trying to apply Bone Settings to bone, clavicle_r, that is not simulated (not between root and effector).

(and so on…)

I had the same problem. I don’t have the exact solution but I’ll describe what I did.
I opened my IK Rig asset, deleted the bone settings (I wasn’t using them)
Deleted the actors that are using the animation with that IK Rig from my scene.

Flood of warnings didn’t stop

Closed the editor and opened again. Now I don’t see the warnings.

Maybe now I can re-add the settings one by one and test.

Isn’t that because of the editor just clearing the log when restarting? How did the test go?
