No Summoner Grade in Match History [Client]

I noticed recently that when I went into my match history after ending a match, no grade would appear next the the XP amount. This doesn't change if I go into the more detailed match report, or use the web version of the report either. I can't for the life of me remember if I got them properly at end game since I usually don't bother looking, but it's a bug nonetheless. Will update if I notice either way on that.
