Question [Q] Alarm Problem

I'm using slimkat on a galaxy s2 i9100

I change the ringtone of the allarm and all is ok, the sound working, the alarm working, no problem.
When i reboot the phone, all alarm ringtone became the default ringtone and the name of the ringtone in the alarm program became a number like 7134.

Any solution?

Thanks and sorry for my bad english.
