Default Alarm clock issues

The alarm clock on the phone seems to work when it wants too. Sometimes it comes on full blast until I turn it to snooze. After snooze it comes back on after the set time I have set and only plays for like 2 or three seconds without me touching it. Then I think after that no more alarm. Anyone else? I'm on latest venom ROM. S-on.
