[Client] Match History Doesn't Update

My match history shows nothing beyond the 31st of July despite having played multiple games each day. I am about to play my 6th game in a row as Fiora, and my match history shows that I have never played her. Programs like Facecheck that use the League API also say that this is my first time, not showing any recent match history. However, https://na.op.gg/summoner/userName=Shady+Blue shows that I have played a couple games as Fiora, with the most recent update being 40 minutes ago.
