2019 CX-5 Rain sensing wiper issues

:
2019 CX-5 Signature Soul Red Crystal
So today was a totally dry day, but on Auto setting, the rear wiper was going for a while, but the front wasn't. What could cause this?
 
You've accidentally operated the rear wiper? The Auto setting only affects the front wipers. There is no sensor/camera on the rear screen so the rear wiper can only be operated manually or set on intermittent.
