Superstar Save Delete

Hello,
My problems have to do with the Superstar career.
I have two games, a QB and a HB who is more advanced. I was playing my QB when the game had a bug and returned to the Superstar choice menu.
Since then my QB save is on my HB save and my QB save when I cast it makes me start over from 0.
The problem is that suddenly I also lost my HB save, because when I click on it , I come across my QB save but not with the correct character/stat.
I don't know if I'm clear, my QB save overwritten my HB and it's put on the HB save slot and my QB slot is at 0.
So I can't even recreate HB anymore without having to delete my most advanced character in the wrong position etc...
I have already checked the files by the way
If anyone can help me, thanks in advance
