Alarm has serious bugs

The alarm regularly goes off on days when I have disabled it. Today the White Noise Alarm (which makes a regular alarm-clock noise) went off even though I have never set that kind of alarm...and the app was completely off, not even running in the background! I can be sure that this is a bug in the app and not user error, because Ive become extremely careful about settng and disabling the alarm ever since the problem started. This ruins days when I need to catch up on sleep --please fix!
