Rachio over-watering my back yard, but not my front. What's going on?

Other than the front is fixed spray head and the back is rotor head, I have both the front yard and back yard set to the same settings. The back is over-watering and it would appear that Rachio knows this. The front yard shows moisture at 30% and the back shows 110%. This time of year, I would expect the back needs to be running between 5 and 10 minutes, three days a week. Last night it ran for 33 minutes. The front doesn’t appear to have run at all.

A suggestion for Rachio. I think they should show the date in the history, in each history entry. My history only shows the time that it started and how long it ran for.

I really just want this to be easy. Any ideas as to what may be going on?
