Can someone explain this loan contract?

So, the Czech team that finished 9th in the league got a ridiculous regen, whom they are giving a professional contract with a minimum release clause of 5,75M€. This prospect is probably good enough to directly be a star player in their team, because now, 1 1/2 year after they got him, at the age of 16 1/2, this is him:

So, being a midtable czech team, they decide to loan him out with 15, to Slavia Prague, they get less money then they are paying him as wage, and he has an optional future fee of.... 30k. Did the AI misclick? What is going on?
