Custom workout time


I added a custom workout (15 minutes, difficultly level 2) to my calender. When I completed it, I got asked if I wanted to edit the time and difficulty. I changed both values to 60 minutes and level 1 and saved it. However, the calendar day still displays the values I set for the workout when I created it (level. 2, 15 minutes). It doesn't update even when I reload the site.

Is that a bug?
