Hi,
Sorry for the issues you are having. I can help troubleshoot this with you.
I tested this out on my test site and the information exported correctly for me.
I got all these fields with the latest version:
Order
Name
Email
Ticket Type
Ticket Number
Security Code
Check in
I noticed in your product list you have this:
The Events Calendar: WooCommerce Tickets, Events tickets plus.
You should either have The Events Calendar: WooCommerce Tickets active
or you should have
Event Tickets and Event Tickets Plus active.
You should not have both active.
Also, do you have any custom coding that would change the Attendees list?
Let me know.
Thanks
