Can't claim reward after completing milestone

So I've been playing my new battlefront 2 and I've really been enjoying it. Untill now that is. I finally got the 200 kills needed to unlock the CR-2 but the game won't give me my reward. It says 200/200 kills but I can't click the claim reward button. I'm sure that I'm online and I've restarted the game serveral times. Does anyone know a fix? I'm getting really annoyed by this.
