Can't Skip Zone Watering

I have several zones that I want to skip the watering for tomorrow. When I click on the day to be skipped, 2 of the evening watering zones do not give me the option to do so. I cannot figure out why. Thank you for any help.

Sorry to be a bother, but if anyone can provide me with the solution to my above issue I would really appreciate it. Thank you so much.

What types of schedules? I only have Flex Daily schedules running, but all my schedules allow me to skip if I wanted…
