Moved data store, seeing many HASH issues in the log as errors (4000+ for each incremental backup)

Hi, we moved the datastore (same UrBackup URL for it), however on backup it looks like any existing data has the wrong HASH and / or it cant find it, i assume running a FULL backup will fix this?

We did alot of data removal by deleting backups before the move, so wonder if its connected to this rather than actually moving the data store.
