Good afternoon Jeremy and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about your events not showing up as you would expect them.
I would love to help you with this topic.
I just took a look at your website and I know what is going on.
The issue is with the single-event slug. This slug absolutely needs to be different than the calendar slug (see attached screenshot)
You can find this under Events -> Settings -> General

Let me know how that goes.
Best regards,
Geoff B.
