One artist being sorted by last name

Thanks for this. It looks like there might be AlbumArtistSort and/or ArtistSort tags somewhere in your library with the value "Bowie, David".

The easiest way to check this is to temporarily remove AlbumArtistSort and ArtistSort from itemTags and add them to indexTags, then restart MinimServer. You will then be able to look in the AlbumArtistSort and ArtistSort indexes to see if the value "Bowie, David" appears and which files contain this value.
