Hi Geoff,
Thanks for replying! Here is a link to a zipped theme file in dropbox. I did revert to the Twenty-Fourteen theme and the problem persisted.

Specifically, I have used this shortcode on the Academic Calendar page [tribe_events_list category=”academic-calendar”]
and
[tribe_events_list category=”board-of-trustees”] on the Board of Trustees Calendar
