That is the way the system works, you pay for the academy and Nordeus charge you for the 4* giving the 2* for free as they are crap.
You release both and Nordeus put themm on the transfer list as a free, so they make the tokens from them both in the auction.
Keep the 2* train until last day of the season and sell him, at least he may pay towards a better player.
Stinks but there is nothing any of us can do.
