Events Widget not working

I am having issues with this plug in. When viewing it on our main page, the widget does not display our link to the event, rather, it displays the title of each page. It was working before and suddenly, it stopped working. Our events page is still there so I do not understand why it does it not work. Our website is:

Please let me know what I can do about this issue.

Thanks!
