Need Help setting up schedule First time user

Does Flex Monthly require you to do advanced settings in your zones?

I setup my zones, on the flex monthly and the next day it set watering to everyday for the month. Is that normal?

In order for the system to compute a schedule it does need information to figure out how much water is needed on each watering (how long) and how often (based on drain and evaporation), so yes you need to fill in all the options and tweak them if the resulting schedule seem to far off
