Twisted Treeline Ranked Wins not counting

Everytime my ranked team plays twisted treeline and win an extremely long close game, usually 30 min+, after the victory screen pops up and we hit next, it shows a screen that says "waiting for stats" with an option to skip waiting for stats. However, the games don't get counted towards our ranked team, but it shows up on my match history as us winning a ranked game. This has happened with two different ranked teams that I am in, and I hope riot will fix this soon. You call look at my match history if needed
