Career Mode Glitch, Created Players

I created a few players and added them to a team (Plymouth Argyle), and all went well until the start of the 2nd season. It was then when i noticed 4 of the 7 players i created were gone, and when i opened the Squad Hub the game crashed. I opened the game again, and searched for the players. The players that came up were all from the wrong nation, in the wrong club, and looked completely different. They were not the same player, but only had the same name.

If anyone has had the same issue, or has any answers to this, please reply.

Thanks in Advance.
