Using eBay GetItem API call I receive the option CrossBorderTrade=GB for an item. When revising this item I see International site visibility set to "-" (I assume it should make this option disabled but it doesn't). Also these settings https://www.ebay.com/ship/prf show Global Shipping Program as Not enrolled.
So the question is: what setting should I change to receive an empty CrossBorderTrade option from API?
Thank you!
