Event URL details Not Working in Popup

This may be very simple, but in “Grid” view when you click on an event and the pop-up displays, the URL link to show the event details does not work. I’ve been trying to figure this out and I’m stumped.
You can view my calendar here:

If you switch to ‘list view’ it works but not in grid view. Any help would be very appreciated.
