Profile > Stats are not updating

I haven't noticed if this occurs with all champions, but Annie in specific has not been updating at all in the Profile > Stats page. It keeps saying "Play 1 more game(s) to unlock stats for this champion" but I've played over 20 games with her now. I even have Mastery level 4 with her but I still can't view my stats. This has been going on for almost a week now, any help on this would be greatly appreciated.
