Basically, anything that was created in the betas and then edited in either 11.0, 11.1, or 11.2 is gone if you go back to 6.3. It's a shame because, now I can't even use my NASL patch on my game anymore. It's just an empty league with a place holder. If you didn't make that many changes to your game, like me, you may not be that far off. The names are missing because going back to older versions of CM leads to the player's jersey name being deleted. SO you have to re-enter the players jersey name. Strangely, this is only the case for players who just use their last name. If the player uses his first name, a nickname, or uses initials (i.e., A. Cole or J. Cole), it's fine.
