[BUG] Unable to execute "Remove Offline Files" on default library for CLI "imported" external libraries

The bug

I migrated immich from NAS1 to NAS2 and the top level path changed from /mnt/Photos to /share/Photos.

Even though I updated .env and docker-compose.yml with the new top level paths (i.e. from /mnt/Photos/immich to /share/Photos/immich), I backed up and restored postgresql DB onto new stack, everything loaded fine, all images display fine, no issues until I attempted to download multiple photos older than July 2023 from own timeline or albums and every time zip file size is 22 bytes...

Furthermore I then noticed that even though the photos load in immich (presumably cached), their location is /mnt/Photos/ instead of /share/Photos - how can I purge the metadata of the externally imported (a while back via CLI tool) photos/videos so that I can re-import it again correctly, via the new method.
