NetworkManager doesn't spawn my custom mesh properly (on client/host)

I built my prefab (not nested) and registered it as the default player prefab, this prefab contains a pistol model. Then I started the game as a host and noticed that only parts of the pistol mesh loaded. After this attempt I launched a standalone server and connected to it as a client only. On the server the mesh displays properly but on the client the issue persists and only about half of the gun loads.

The image below is on host.

The left is on server and the right is on client.

Here are the components I attached to my prefab.

Here is the network manager and its components.

Here is the network manager script with some of its details.

@LukeStampfli I think this one is more on the dev side than Docs

Not sure if this is related to MLAPI or not just some other rendering issue

We cannot repro this issue, and as Luke stated, it seems like it may be unrelated to the SDK.
