This is actually expected behavior, however there is often confusion here. Rain Delay is actually a different feature than Rain Skip, which is what is causing your schedule to skip when it rains. Rain Delay is not related to weather, and is just a manual stop on your system for a given number of days. Rain Skip is a feature that is enabled on your schedule that watches the weather and skips when you reach your threshold. I hope that helps clear up the confusion there!
As for your water savings, are you still not seeing a value there? Is this not showing on web, mobile, or both?
