Ringtone jumps back to Horizon after reboot

[Bentrovati]

Hi all,

The ringtone settings of my wife Node Edge is jumping back to "Over the Horizon" after every reboot or after an incoming call.
I tried to change it to one of the other default ringtones of Samsung, but after a reboot the ringtone is set back to "Over the Horizon".
I also tried using a custom ringtone without any luck.
I removed the SD card, change the ringtone ... also without any luck

Can anyone help me to fix this issue without a factory reset?
Btw. I have the same phone and I don't have any problem with changing the ringtone on my Note Edge

Specs
Samsung Note Edge
OS 4.4.4

Your help is really appreciated
