Harry (Quidditch) token glitch?

[Aelon77]

Hello,

 

I’m missing one token to get the 100% on this game, but I can’t manage to make it appear even though I dig the 5 dirt piles in the flying lesson zone.

 

I can hear a sound which might indicate that the game registers each time I dig one of the piles, but there’s no « 1/5 » popping up.

 

I haven’t seen this glitch anywhere so I don’t know if I’m unlucky to get it or I’m doing something wrong…
