[CLIENT] Friend List "Recently Played"

Everyone I know seems to be experiencing an issue with the Recently/Frequently Played display on their friend list. For many of my friends it just shows them as having played either "Random" or "No Games Played". And myself for example it shows me as having played Sona, even though I've only played her once in the last couple hundred games. Prior to that it was Garen, with whom I played exactly once in a bot game.

It's obviously not a big deal or anything, but I can't seem to find any other mention of it on the boards so I figured I'd at least bring it up.
