Thank you for clarifying this!
I now see what you’re trying to do; this is unfortunately not an out-of-the-box feature, and the “Custom Ticket Fields” from within The Events Calendar are not added to the “Custom Fields” of WooCommerce Orders.
The similarity in name of these items is something we might be able to help clarify, as it might imply some sort of relationship between these two things.
But there is unfortunately no such relationship at this time. 🙁
Sorry to disappoint about this first question—if there is anything else I can help with or help to address, please let me know.
Sincerely,
George
