Players keep getting released

[madden07eurocat]

I start out with 52 players on my regular squad. I add a FA to the roster and if I go into a game or into practice, he gets released to FA again. I do this with multiple FA being added. I even added a player from the PS and then he gets released. I can never go into a game with a full roster because the game releases the man that I just added to the roster. Has anyone else had this happen and what do I do to solve this issue?
