Subject: I can't sign my junior players

Hello!
Somebody help me.
I can't sign my youth players.
2 weeks ago I had a junior player whose skills were not yet good enough, so I thought I would wait another week with him.
That's what I did, but since then it won't let me, not even my better-skilled player.
The system says: Error: Double junior promotion.
Who do you think I should write to or what should I do? Has anyone been in a similar situation?
Thank you in advance for your answers.

did you try to log off and log in again ? usually it helps

so I thought I would wait another week with him.

Also - juniors don't train in YS anymore after reaching week 0. Don't wait to pull them.

is this true for sure?
I have seen pop ups after you leave the junior with 0 weeks, so it might be just a pop up without training (as we don't know the exact junior skill), or it might be training.
I have never tried to leave a guy for a season or something like this, so not much info about it.

It's an (incorrect) estimation of your coach, no actual improvement of the junior.

+1, this

Thanks, problem fixed after reboot.

He went one level higher though. True, it relapsed the following week.

Just an estimation
