2beta5 and sound

Some how we created a sound notification with 2beta4, and now we are running beta5. We want to change the sound file. So we followed these steps, and get an error:

open notifications fromthe left panel
since our sound notification DOES NOT appear in the notification window, we hit +
select sound, and the foward arrow to hear the sound.
It plays just fine, and we hit test, plays just fine.

Then hit OK.
Get this error:

already have object with same name.

How do we totally delete that object and create a NEW sound notification.?

Thanks

anyone have an idea, is therre a sql schema to edit, or where is the notification entry stored that we are not able to see.

well theoretically you should be able to export your configuration, then edit the generated xml file, and import it back. We are interested in how you got this situation. Can you reproduce it?
