Are the other deactivated schedules Flex Daily schedules? You can have a zone in both a Flex Daily and a fixed, but you can’t have it in 2 different Flex Daily schedules. Not sure if even though they are deactivated that they are locked out since they are probably still processing data on the backend in the event you bring them live again…?
Thanks, @tmcgahey - That was the problem. I had to remove the grass zones from a deactivated Flex Daily schedule before it became visible to my new schedule.
