Hey Steven,
Sorry for the trouble here.
I’m having a tough time replicating this on a fresh install of WordPress using the Twenty Fifteen theme (screenshot).
By chance, have you customized any of the calendar templates? You can check by heading into your theme directory and looking for a folder called tribe-events. If t here is a folder in there, what files do you see?
Another way to check would be to follow the steps outlined in this article. That’s actually a good idea because it will hit two birds with one stone: check for customizations and for conflicts with the theme and other plugins at the same time.
Let’s start there and see what we find.
Thanks!
Geoff
