editing prices

How do I change the prices in the booking calendar? When I first initiated it, I set a price for each day in the calendar. Now I want to change them and I can’t figure out how to do it. When I double click a day on the calendar it doesn’t let me edit and the edit button just goes to a reservation box so that is useless. I remember clicking on each date or a series of dates and inserting prices but that doesn’t seem to be possible now. Please help. Running 3.8.1
