Good afternoon Patrick and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the display being real wonky on your site.
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?

Secondly, I would recommend trying to head out to Events -> Settings -> Display and trying out different settings for the Events Template option.
Finally, try temporarily reverting back to a default WordPress theme such as twenty-sixteen and see what happens with the layout of the single event.
Let me know how that goes.
Best regards,
Geoff B.
