Solo Battles Glitch (Not allowed to play last game) 3+ weeks issue.

I was ranked #22 in Ultimate Team Solo Battles with a “Battle score” of 276,996. I played only 12 games. There are 13 games available every week for every user to play. I clicked onto my 12th game with the 13th game available to play. After completing my 12th game, the screen went into a “Rewards Pending” screen and this screen made it so i lost my opportunity to play my 13th game. I was ranked #22 and i could have made it to #3 on the rankings if i had just played that game and won! But Madden eliminated my opportunity to even play the game. And it was a game against a 77ish ovr opponent too. Does anyone have help for me? I would like to play this game and move up the rankings. This glitch is really upsetting to me
