I still don’t know why this happened, but here’s what I did to fix it. I think it has something to do with the permalink.
1) I created a new venue with the same name. which has a different permalink, but the exact same details.
2) I was able to select it from the “My Venues” section.
3) The event now shows up.
Here’s the two different sections from the Venues dropdown. They are in the same list, only separated.

What are the differences between these?
Why does the listing now display?
Thanks.
