Ok I recently ran into an issue that I figured out on my own that I thought I would share. The V10 has ringtone ID where if turned on there is a generic ringtone that you cant change for all favorites. It is a different ringtone then the regular callers in your phone book. To disable this go to settings/sound & notification and turn off ringtone ID. It would be nice if you could edit the default ringtone for this feature instead. Just thought if others struggled with this and had the same issues as me.
