[Q] Ringtones/Alarm tones topic

I've been running into problem, where at random intervals my alarm clock, Gentle Alarm, and Ringo both seem to lose their custom ringtone/alarmtones and revert back to defaults. I've tried blocking them from being closed by the battery saving software, and then they seem to work for a few days. Ringo still works, but Gentle Alarm just reset itself again. Any ideas?
