Can't settle the last game in a round of Gauntlet 4 tournament

I have won two games in a round of Gauntlet 4 tournament, but when I tried to finish the third game（I tried many times for a few days）,I was kicked out of the Utimate Team mode., which stops me continuing the game and prevents me finishing the remaining task of "9 goals" and "12 matches". The reason is likely to be the data dismatch and confusion after the completion and reset of the  Gauntlet 4 tournament, because I find that although I have finished two games in this round, only one team have been marked as "used" instead of two, so I wish you check and solve this problem asap.
