I lost points after 1v1 win ranked games (-1)

Dude, after winning the game I still lost -1 Elo point? What’s wrong with this game?? This patch fixed nothing!!

Sometimes it doesnt say you lose points when you lose it takes it later so if you lost and should have lost 19 points and next game you won for 18 you are on -1.
But its only visual bug if im not mistaking.
