Howdy cgarwriter,
Hmm. It would appear that this is not even an Events Calendar page. Do you perhaps have a page or post elsewhere on your site with the slug “event”? It would appear to be loading that instead. We should probably delete it. If you click through to this page, you should have an “edit post” link in your WP Admin toolbar. Click that, then click send to trash. You should probably then visit your trash, and click on the checkbox next to the post then click “Delete permanently”. Once that is deleted then try flushing permalinks as outlined here (different problem mentioned but the steps it walks you through will work here too).
Did that work? Are you seeing the events pages now when you click Find Out More?
