Figured this out in the end and it looks to be a mix of the following
- The ArtistSort field of the tracks was populated differently to Artists
- Jellyfin couldn't match ArtistSorts and Artists together so listed them as separate entities
- To correct the ArtistSort field had to be changed and then the albums needed a re-scan for updated metadata
- On some Jellyfin got stuck but after correcting them it seems to have stuck
