Ukraine player registration

[linuxe]

So here's the thing.
I'm in a save with Shakhtar Donetsk, and every season when the player registration period is on, the minimum players that have to have played in Shakhtar for three years before turning 21 are changing every season.
First it was a minimum of 4 players, then the second it was 6, and the third it's 7.

Am I missing something from the Ukrainian player registration system or is it a bug, or what's going on? Really frustrated...

Sounds weird, maybe ask the bug thread....

Didn't know where to put this since I'm not sure if it's a bug or a part of the system.
Hopefully some Ukraine expert can sort this out for me .
