Hi Mark!
Thanks for getting in touch with us! I’d be happy to help you troubleshoot those issues.
First, please let me note that we’ve just shipped a new release of Eventbrite Tickets 4.5. You will now have much more control when importing Eventbrite.com events into your site.
You can find out more about this release → https://theeventscalendar.com/release-the-events-calendar-4-6-18-and-eventbrite-tickets-4-5/
We always recommend using a staging site to test new versions before updating on a live site > https://theeventscalendar.com/knowledgebase/creating-using-wordpress-staging-site/
Could you please share with us, in a private reply if you’d like, the link to the event where the tickets are not showing up?
As for the additional options, you will need the following extension to make those options show up > https://theeventscalendar.com/extensions/eventbrite-additional-options/
Please let me know how that goes.
Thanks,
Victor
