Schedule Problem

I’ve been using my Rachio 3 for over a year. Setup a 6 zone simple system using flex monthly and let Rachio decide the rest. Recently I had to remove Tuesday from the schedule and when I tried to do that now instead of 3 days per week it wants to water every day except Tuesday. Then somehow in the process of changing things I decided to modify a zone soil type and it proceeded to adjust one of the zones from about 20 minutes to only 3 minutes. Finally after manually setting the zone times to fix that I have ended up with my days and my times instead of any of the previous Rachio flexibility of days and times.
Seems like once you adjust something you can never get back to any dynamic scheduling. What am I missing and how do I get some flexibility back in my days and times?
