Unexpected watering

I had turned off the schedule on my rachio and had no active schedules. Today my sprinkler system went off and for some reason one of the zones was watered for over 600 minutes today. My neighbor came over to tell me he saw the front was on for over an hour.

I don’t know how it went off when it was not scheduled to and Im not sure why it watered a zone for over 600 minutes. Is there some way to troubleshoot this so it doesn’t go off unexpectedly?
