Fitness doesn't go up

Second season Be-a-Pro-modus.

My fitness just doesn't go up. In the training-screen the blue-line is at 100, but for the race itself it's just at below-average.
I don't think that I'm doing something wrong. Could be a bug?

Restarting the game helps.

Hello, i had the same problem, but the problem is that you rider have some objectives. And if you take part to another stage before an objective, your rider will have a very bad fitness has when you manage your team and rider ! On pro cyclist it's the same. I hope you understand my bad english

No, this is not the problem. It's just a bug.

Same here, clearly a very bad bug........
