When a customer selects shipping details "Same as billing" during checkout, some of the fields (3 shopper fields I created, "buyer type", "production" and "EU vat status"

I have added the specific fields for billing and shipping addresses (as per this suggestion by tharuna on this post: https://csvimproved.com/forum?view=topic&defaultmenu=1054&catid=44&id=34599&start=0) and updated my available fields but the data is still not there.
CSVI Pro 7.11.0 (incl. Virtuemart)
I've attached a copy of the template, debug and a sample of the exported file.
Thank you in advance.
