PUBLISHER tag in Index Tags trouble

[simbun]

MusicBee's Tag Inspector (Right click on track > Edit > Tag Inspector) is a great tool to have on hand in these situations, as it displays the raw field names alongside the "user friendly" alias.

   

If I'd used it myself in this instance I might have have spotted my typo (organiSation)!

Better yet, if you're working with MinimServer you can enable the writeAllTags option and it'll produce a listing of tag name(as used in MinimServer)/value pairs.
