Ranked team does not getting lp

So we have played team ranked games and everytime we win we are not getting any LP and it freeze after game on waiting screen, and that game cant later watched from match history. It shows that game and date but when click it "Select a match to view details". But when we lose, it shows stats screen and how we lose LP. and that game can be watch later from match history. So is this only us or some bug?
