Hi John!
Thanks for reaching out to us! 🙂
Our plugin’s templates show the start and end dates by default, so it seems your theme is making some template customization that affects this.
It’s posible to show the end date of an event by customizing our template files. There is a great article on how to do this here > https://theeventscalendar.com/knowledgebase/themers-guide/
If that does not help, you might want to check on your theme documentation and see if there’s a way to do that. Or event contact your theme authors and ask them about this.
I hope that helps! Let me know if you have any other questions and I’ll be happy to help!
Cheers!
Victor
