[Client] [Website] Match has not been recorded in match history

I have just finished a game in URF playing as Amumu in which my team got First Place and I received a chest for my S+ ranking. However, when I happened to glance at my Match History tab in the client, the match does not appear, only the Amumu URF match from yesterday, while the Champions tab did record the match and shows my grade from the match and the Hextech Crafting section of the client has the chest that was earned as well. The website (matchhistory.na.leagueoflegends.com) does not have a record of this game either.
