Last night after winning a game of solo q, the client kept thinking I was in game, now win is erased

I won my second to last promo game last night, and afterwards the client kept thinking my user was still in a game for hours. When it finally understood I wasn't, the last game was still recorded in match history, but the win didn't count. I won another game today, and I was still 2-2 in my promos after that game.
