Good morning Rhonda and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the layout of the events list not displaying properly in the backend of your site. I would love to help you with this topic.
This is typically caused by too many columns competing for space (especially on installs that have Yoast SEO present).
The good news is that you can easily fix this by removing unnecessary columns using “Screen Options” and turning off the Yoast columns (see the screenshot below – it’s for the menu screen, but the principle is the same)
Let me know how that goes.
Best regards,
Geoff B.
