Ring tone reset to default

[CyberZeus]

Hi, every time I restart my Xperia J, the ring tone and the notification tone are reset to default ones.

Is there a fix for this?

Thank you

Is there ring/notification tones stored on your SD card or is it default ones? 

If you are using ringtones from the SD card, do you experience the same problem if you change the ringtone to a standard ringtone stored on the internal storage?

The ring tone I use is "Big Easy" and the notification one is "Palladium".

I think they are standard ringtones in the internal storage.

Do you have other suggestions?

Thank you
