Playlist ordering issue when adding a track

In the android app, if i choose to add a song to a playlist, it brings up a list of all my playlists, which can be sorted either alphabetically or by 'recently updated'. If i sort alphabetically, it sorts by upper case first, A-Z, then lower case a-z. This is a very strange ordering, and is quite annoying as at first it just seems like half my playlists are missing, just arbitrarily based on whether i happened to name a playlist with a capital letter at the start. I can't imagine this was intentional as nobody would ever want to search in this way, and it's not consistent with playlist ordering in other parts of the app (e.g. in the main Library section, if you go into Playlists this is ordered correctly in true alphabetical order, regardless of case). Hope this can be fixed with a future update?
