Date unsorted

[mcgillroy]

Having a strange issue here & no idea what causes it. The Date tags appear to be sorted randomly.

My properties are as follows:

Indextags: KlassikGenre=Klassik:Klassik Bibliothek, ComposerSort:Composer, Composition, Conductor, Genre, Group, +Date, Artist, AlbumArtist, All Artists, Orchestra, Soloist, #AudioData:Music Info, #AudioQuality

ItemTags: Composer,TitleSort,CompositionSort

tagOptions: Date.yearOnly.*, Album.sortTags={Date,Artist},all.ignore.sort={The,A,An,Der,Die,Das,Ein,Eine,Le,L​a,Les,Un,Une,Il,El}

tagCustom: AlbumArtist.displayRole={artist}, Composer.displayRole={artist}

tagUpdate: /Volumes/Tunes/tagupdate.txt
