If you have only chosen S, W, F for flex schedules, then it will only run on those days.
If you contact [firstname.lastname@example.org] they can help review your account and help determine if the correct attributes have been chosen for your particular zones. Without seeing your actual layout (crop types, nozzle types) it's tough to give an exact answer.
One thing to note on flex schedules, the more they are limited (i.e. only a few days per week), the less value you will see. Flex schedules will know that you can't run until a certain day and might try to top off the zone until the next watering day. The best case for flex is any day, so they can run flexibly. Just a heads-up. I understand the restrictions you have put in place by the city. You can experiment with both (fixed/flex) and see which works better.
[email@example.com] can also help you dial in the system if you need it.
Thanks and have a great day.
