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.
