Timely Calendar Doesn't Allow for Going to Previous Page

I have two time.ly calendars on two different pages of my site and for whatever reason, the browser’s back button doesn’t work on those pages. Any suggestions on how to fix? Because I have no idea.

It’s the Events page and the Start Playing (under Get Involved)

Wow, that behaviour of that widget is horrible. Perhaps you’ll want to submit a bug report for the third-party plugin you are using, as we won’t be able to do anything about it.
