Playing with the old and the new version (tips or traps)

I didn't understand what you mean.
If we set a training in the new version and have some gaining and then we go to the old one, the blue bar is reset ?
If you mean that, I don't think so.
I have a player, he is a scout list player who now is a (early) 7* player, so he isn't fast trainer.
After a game, he won MoM, and a +7.
4 of them was from MoM (the old +1 sp) so the other 3 must be from the gaining of the game.
But that mean the blue bar cannot be empty as this player couldn't earn so much progress in a game.

I cannot exactly remember what I have done in new version. Most likely I have trained my players. When I returned to old version, I clearly remember the training progress bar of all players are empty in old version. I did not further investigate but cease to use new version to avoid losing training progress.

Though there is no sp now in new version, I believe that it still need to store training progress for training effort which is insufficient to add at least 1% to some attribute. I really don't understand.
