NHL 16 change stats to originals

[GGtaco7]

In NHL 16 I changed the player's stats on the Grand Rapids Griffins, now when I'm playing on the "be a pro" game, the Detroit Red Wings are bringing up players from the griffins and it's ruining the game. How do I change the player stats back to their originals?

To clear things up, I'm playing on an un-updated version of NHL 16. I changed the stats of all the Griffin's players to 99, making an overpowered team. When I played my be a pro career, the Red wings, (their NHL affiliate) started bringing up players from the minors, making them too good. I want to get their stats back to normal, without having to do each by hand.
