FC league - Matchmaking does not work

The cup matchmaking is bugged. I played 7-17 and I’m in Division 3 – so tell me that this system is working: 70% unbeatable, 20% 1 goal difference, 10% penalty shootout. I played against an Elite Division team in the last game. I want to report a bug – this matchmaking does not work! I lost and got stronger opponents than before. There must be a mistake! This is a serious complaint, so please check this. We also need a counter that shows the points.
