Calendar workout complete

I added a program to my calendar and each day when I complete a workout, I press “workout complete” but wen I go back to calendar view, it stays blue. So there is no difference between the upcoming days (circled in green) and the past days that I completed (circled in red). Is there a way to see the ones you have already done? Like a check mark on those days or something? Am I missing something?
