The "Recently Played" feature is bugged

A week or two ago, I started to play a ton of Kindred and I saw that no matter how much I played, my "Recently Played" tab still said that I was playing Irelia top. I thought it was just the result of me playing a ton of games with Irelia, but I recently bought Lissandra and have over 15 games with her. I, again, thought my "Recently Played" tab was just reflecting what I had played a lot earlier, but then I played just one game with Bard and it said my recently played was Support Karma, which is funny cause I haven't played Karma in over 3 weeks. Is anyone else having this problem?
