Mutable - Object Mesh Relocation

Hi everyone, i am using UE 5.5.4.

Question 1:
How can i relocate a object mesh in the Mutable system (example Ponytail hair) to correct the location to the body of character mesh?

Have allready tested many posible solutions from many tutorials, but nothing help. See at the Screenshot (it is just an example).

Have some Meshes they need to relocated, how this works?

Question 2:
How can i make the result of an Mutable to a specific character in Multiplayer?
If i change something (like switchting Ponytail to Long Hair) every Player in Multiplayer have this changes. But i dont want!
Every replication methodes dont works, everything is allready auto replicated to every client. Is this a missing feature or a bug in the mutable system?

No one have this issue of wrong placed actor meshes they are not scale or move with body size?
