Snapshots used at 60% without having snapshots

[damilew]

Hey Guys, Im using a qnap TS-431p (FW-5.0.0.2055) for a small local business storage and I've run into a major issue I can't manage to resolve.
It appears the storage pool got filled with snapshots that don't exist and I cant find a way to delete them...

Does anyone know where these snapshots come from and how can i get rid of them? I did format the qnap a while back...
