The solution presented in this thread (https://projectdmc.org/support/topic/custom-fields-does-not-appear-on-backend-orders-page-or-email/#post-17054845) did not solve my issue and I have the same exact issue- custom fields are not showing on the backend, orders or order email.
I have confirmed each field has its own unique label.
Please advise 🙂
