Calendar Block Not Updating

I have recently added three events during the week of October 3 - 7, 2016 as content type “Event” and they do not appear in the calendar block on the page, http://sustainability.yale.edu/participate/celebrate-sustainability. I explored within the dev.sustainability.yale.edu and found a custom view that was created “April Only Events Block” as we used to add calendar events for a week in April. I tried to clone “April Only Events Block” to create an “October Only Events Block” and created a test event but it still did not appear on the calendar. The calendar block also showed upcoming events last year and currently does not. I unpublished all of the past events I created.
