Hogwarts Legacy Trainer fix necessary?

[Kttekassitar]

Everything was working fine, and then I discovered a game-breaking feature :
Those big house medallions/ flying keys medallions - when you open the first one and put that in the house chest, for some reason he lets you put them there endlessly and even if all the slots are full, the quest doesn't end, because you actually only have 1 correct one.
To be honest, I'm not a moder and I don't know exactly how this thing works, or what causes it?
But can it be fixed?Or what trainer option might cause it???

Has anyone had this problem, what do you suggest to do, advise me, share your experience?!

Thank you.

For those who have the same problem, I got them working like this -
I took the save file back to the point where the quest was not activated, turned off the trainer and looked up all the keys and finished the quest. And then I activated the trainer again, and the game continued.
