Good evening John and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

It sounds like you might be using our Event Tickets plugins which is responsible for your tickets showing up as free.
You could apply the following snippet in the functions.php file of your theme (without the PHP tag at the top): https://gist.github.com/GeoffEW/69f8a033fb614c78b3de45a197431135
But first to be extra safe, before making any changes to your functions.php file, you should make a backup of that file.
Let me know how that goes.
Best regards,
Geoff B.
