We are getting caught out with this all the time. When a customer updates their address, it does not change in all views.
Please make sure the latest customer address is shown in all views:
  1. Packing Slip
  2. Subscription details (where you can see no of orders, survey data and payment details).
It's view number 2 that we use due to needing survey data, and this does not show the customers latest address.
Thanks
