Ultimate Gauntlet issue

I won the ultimate gauntlet and started my second entry. I lost in the first round. My entries refreshed but I couldnt use the players i had used in my previous attempt. I lost this match and used my second entry, I couldnt use any of the players i had used in my previous two attempts. I won this fixture and after the game it said the tournament was completed. I had no more attempts and did not go to the next match
