Events show the main event listing page

Hello. All of my events will show the main event listing when clicked on. They share the same permalink /shows/ but the rest of the link is different. The main event listing page is https://chrisruggierosings.com/shows/

One of the event URLs you can check out is: https://chrisruggierosings.com/shows/stars-of-the-sixties-in-clermont/

If you visit the main event listing page: https://chrisruggierosings.com/shows/
you can see that if you click on an event the URL changes, but it displays the same page again, the main event listing page.

The page I need help with: [log in to see the link]
