Mutable Plugin Replication Issue

I’m trying to replicate the Mutable Customization Object Parameters through the network. The Issue in my code is that the Object Instance created is the one applied to the other users. As you see in the Last Picture, the right is the Server and the left is the Client. All the other users have the same Instance that I customized locally; each one sees their own Customizable Instance applied to other people.

Does anyone know the issue or have a better approach?
