Why doesn't networking animator work with clients

I'm building a simple connect 2 player models that can be moved with only 2 animations. Idle and Run.

Everything works perfectly for the first player to host the match either Lan or matchmaking, but for any player connecting after, their animation will not play if you run. The character will still move and you can see their transforms change, but I'm not sure the issue.

Even when watching in the inspector, the client's animator does show a value change in the integer parameter, but the character will not display any movement.

Thank you in advance!
