iTunes 11.4 (18) won't erase deselected music from my iPhone 5s 64 GB running iOS 7.1.2.  I just deselected every playlist, artist, album, and genre and synced, but all the music I had on the phone is still there on the phone after the sync.  iTunes thinks there's 28.5 GB available, but if I sync again with new music, it gets stuck and says there's not enough room.
Also: if I manually delete music from the phone, then sync again, it puts those tracks back on my phone.
Ideas?
