Order admin: show Customer custom meta data

I created a custom field in WooCommerce checkout for VAT numbers. This value is saved in User Meta.

I need this value to show in order admin when creating a new order on selecting customer. So same as Billing and Shipping details but then the VAT number.

Already have a field beneath Billing details but I cant get the value to show. I get the value when a customer places a order but not when I create the order in backend myself…

Going crazy here! Please help.. Thanks in advance!
