I recently changed one of my programs to run every 3 days.  In making this change I also wanted to change the next run date.  At first I tried to make the change to the next run date using the Android app.  After making the change I would go back in to check it and it would have a different date.  I figured maybe it was an issue with the app (https://support.rainmachine.com/hc/en-us/community/posts/360007144654-It-won-t-let-me-change-the-next-water-date-?input_string=Problems%20setting%20next%20run%20date).  So this morning I tried to make the change on the Rain Machine device itself.  I'm encountering the same issue.  Here are the steps.

Edit the program

Click on Frequency

Next run date defaults to 9/29

Click Change next run, change it to 9/28

Click back

It shows the correct next run date (9/28)

Click back (clicking Start Time, Frequency, Cycle & Soak, .. from here shows the correct date)

Click back (we're now back to the program list)

Clicking on the program it now shows the wrong next run date (9/29 instead of 9/28)

My Rain Machine is running firmware version 4.0.925
