Missing a zone

Weird behavior… I have 6 zones, 2 of which are my front trees and backyard trees, 2 for shrubs and 2 for cacti. We are running Flex daily and using Weather Intelligence Plus to input for precip. Has been working well this far, but….

For some reason Rachio has scheduled my cacti to water within 4 days of each other. It is scheduling the front trees 1 week from the last watering, which is about average historically. Inexplicably the schedule has the backyard trees waiting 2 weeks.

We live in Arizona and it’s consistently in the 100-109 range right now.

Has anyone had this happen or have a possible explanation?
