[GAMEPLAY] Series bug

Hi, so what happened is before the patch i ended up ended up being 2-2 in my series to diamond. Since ranked queues were disabled i decided to go to bed for the night and play my last one in the morning. Well, I woke up and played another game just as I planned and we won. Now I'm thinking that I've finally made it back to diamond but next thing I know it says I'm back in my series... I dont understand what is going on. Did I do something?
