Hi there,
I’m sorry to hear that you’re having issues with Eventbrite tickets. I will try to help you get this sorted.
When using Eventbrite tickets, the event assumes a 1-to-1 relationship with the event on eventbrite.com. I’m not sure it will be possible to duplicate an event that is already associated with an eventbrite event without running into difficulties, as you have discovered.
You can create an event on your site and then publish it to eventbrite.com, but once connected, you would need to delete the event to remove all connections. I’m not aware of any other way to remove the Eventbrite ticket completely from an event without going in and removing the associated data in the database.
Sorry I didn’t have better news for you. Please let me know if you have additional questions.
Thanks,
Sky
