If you turn on the smart zone feature, Netro will skip the schedules(including manual schedules from user programs) when there is a chance of significant rain(>0.2inch).
Netro gets the weather information from DarkSky. Sever side gets and updates weather information every early morning at 4 am. I think what happened is that when you check the schedules last time the are not re-calculated yet. Netro will check the weather data for the past and get new weather data at 4 am in the morning to adjust following schedules accordingly.
