Pro Clubs Matches!!

Me and my squad are playing pro clubs and every time we win (or opponents disconnect after losing) our victory wont count!! We were playing play offs and we had 1 game remaining and we were winning 4-1 to the 90th minute winning the match fair and square and it still said 1 game remaining to then us losing our last game? It’s so script, what happened to this game

PS.It happens in league matches too (promotion matches especially!!)
