Default [Q] Kies: when I transfer music to phone, all artist/album info disappears.

In 'Library', After all of my hard work to add all of my songs' info (Title, Artist, Album, Track number)


Once I 'Transfer to Device' it all disappears, and the 'Title's are just the names of the files, like '01 - Aberinkula.wav'
(And from that point it does not allow me to edit any of the files' info)


Any tips on what I'm doing incorrectly?
