Why have my zedge settings all disappeared overnight

[AC Question]

I use zedge sounds on my contacts and alarms overnight the settings all went to default. What is interfering with my zedge app.it happened about a month ago as well. Had to Uninstall zedge app and reinstall and reset all sounds. How do I stop this from happening again.Galaxy core phone.

Welcome to the forums. Are you using an SD card to save those notification sounds?
