Can't edit "Target Event Date"

Hi All,

I started using XERT yesterday because of the new feature “XATA”. I have tried many times to edit my “Target Event Date” but to no avail. To solve this problem, I have used Internet Explorer, FireFox, and Yandex. How can I solve this problem? Capture

I had trouble with that too & had to clear my browser cache in safari to get the change to save.
My Fitness>Goals>Target Event Date. Then use the calendar to pick the new date, click the blue check mark to save. Right?
