Lost ringtone setting after SoftReset

[chaka]

After upgrading to the latest Helmi Wm6 w/ the kitchen,
seems like everytime i do a soft reset, my preferred ringtone for incoming calls gets reset to the default ringer, not the ringtone i want.

Is there a registry fix i can do to keep the ringtone selection i chose so that soft reset doesn't revert it back?

thanks.
