Hi Gray!
Thanks for getting in touch with us. Let me help you troubleshoot that issue.
I could see your site now showing the prices accordingly, which makes me think you rolled back to a previous version of our plugins. Can you confirm this?
I can see from your system information that you have two versions installed simultaneously for Event Tickets and The Events Calendar. So be careful of not activating them at the same time to avoid conflicts.
We always suggest to setup a dev/staging site so you can test things out and make all plugins, theme and WordPress core updates without disrupting the live site.
We also encourage to make a full backup of your site, both database and files so in case something goes wrong you can always restore your site.
Could you please send me a screenshot of the ticket editor (while on the edit event page) so I can see the tickets for the event and their stock ? You can do so in a private reply if you’d like. I will try to recreate the issue on my end and see what I can find.
Thanks,
Victor
