Hi there @Gporto,
Welcome to the Community!
I just want to double-check a few things with you. Could you please confirm if the "Billing address" and "Shipping address" are custom fields in your WordPress setup? Also, are you using the "New User" trigger for WordPress?
If that's the case, I'm sorry to say that we currently don't support custom fields for the "New User" trigger. But don't worry, we have a feature request for this. If you'd like, I can add your name to the list of users interested in this feature. Just let me know!
Thanks!
