Good evening Karen and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the display of your Edit Events screen being wonky. Yikes!
I would love to help you with this topic.
What is going on is that there are too many columns fighting for space on that screen (typically as a result of the SEO plugin).
The good news is that this can easily be fixed.
What you need to do is head over to theย Screen Options menu (located at the top right of that screen) and uncheck unnecessary boxes. The display should return to normal.
Let me know how that goes.
Best regards,
Geoff B.
