Custom field hook not appearing in PDF attached to email

Hi, I read the FAQ and support guides and forum, but didn’t see this issue. I followed your great guide to use code snippets to add a meta custom field to invoices. It looks great when I generate it from the Woocommerce orders page (under actions) and I can see the custom field correctly. The previews in the PDF Invoices plugin show the field correctly. I have the invoice set to attach to: New order (Admin email). But that invoice pdf doesn’t have the custom field.

I tried checking the box ‘ Always use most current settings ‘ in settings: documents, but it didn’t help. Please let me know what I can share or what I should try. THANKS!

If I can share the code that I have in code snippets, please let me know if there is a preferred way other than to paste it in this text.
