Multiplayer text Chat, based on Command and ClientRpc not working.

I am currently working on a simple text chat for my multiplayer game. The problem is that the chat message only appears on the client that sends the message, but through my ingame Console, I can see that the Debug.Log in the ClientRpc gets called on every client, so every client gets the message, but only one of the clients (the client that sends the message) gets the message int the chat. Here is my text Chat script: Thanks for your help in advance.
