Inconsistent PhysicsJoint prefab vs non prefab

[keen ember]

Anyone else getting oddities where prefab PhysicsJoint's have slightly different baked data to the non prefab entities? Basically I have a character ragdoll, one in scene as a regular entity, and also a baked prefab.
The baked prefab has slightly different BodyXFromJoint axis settings, which I am unable to determine why. I've applied any changes to the prefab so the scene character and prefab should be identical.

That is to say any entity instantiated from the prefab also retains the new different data, its the original scene character that has the correct data.

left is prefab, right is non prefab. both inspector screenshots are taken from the live converted scene(not playmode though)

alright some more testing appears to happen when physx joints are baked, not getting the same discrepancies with the custom authoring package
