Possible schedule display bug

So when I view the zone overview in my app it says the next watering for 2 of my zones is 5-19. However. When I tap on the watering event for 5-18 through the calendar it shows those same 2 zones will run. Is this a bug?

I checked again and it is matching now. It wasn’t matching for a good 2 hours though. I checked a few times.
