Quick run ran on its own?

I am a new rachio user. I have a rachio 3. I set up a Grass Schedule and use flex daily. This morning I noticed at 3am the quick run activated all zones for 3 minutes. I never started a quick run. Is this automatic? How can I stop it? I don’t mind the schedule I created running when needed but the quick run included all zones and my schedule doesn’t use all zones (I have a zone with a broken sprinkler head so I don’t run it). Everything in search says quick run is not automatic it needs to be started manually and it can’t be scheduling either. Everyone was sleeping at 3am so no one manually started it. What happened?
