What does UBL-CR-295 mean? A UBL invoice should not include the SellerSupplierParty

Why did my invoice fail UBL-CR-295?

The cac:SellerSupplierParty element is not used in EN 16931 and should not appear. The seller (BG-4) is carried exclusively in cac:AccountingSupplierParty; SellerSupplierParty is a UBL ordering-role element outside the core invoice model.
