Hi Bennie,
Thanks for using our plugins. I can help out here.
Imported from Eventbrite
Once an event is imported it does not reimport changes from Eventbrite to your install.
The tickets will update on the front end, but not title or description.
Exported to Eventbrite
If you create the event in WordPress and then export it to Eventbrite the changes should then go from WordPress to Eventbrite.
I tested that way and it worked for me.
For more details on all the settings please look over this guide:

Let me know if you have any follow up questions.
Thanks
