Cant get rid of old alarms

I want to like this app, its pretty and the alarm sounds are nice. But I cant deactivate old alarms. When I was testing this out, I set a number of alarms, and though Ive deleted them all from the alarm page, and the alarm icon in the upper left has a slash through it (to indicate no alarms), the alarms still keep sounding! Ive even uninstalled and reinstalled the app, to no avail. There is no technical support, the website for the company is non-existent. Too bad, it has promise.
