Good evening Daron and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the event having randomly duplicated on your site.
I would love to help you with this topic.
There are 2 things you can do to fix this:
- Head over to the faulty events “Edit event screen” and simply re-save them (individually). That will trigger the recurrence rebuild for them
- If that does not work, I would recommend installing the following plugin and triggering the rebuild manually: recurrence-rebuild-helper
Let me know how that goes.
Best regards,
Geoff B.
