What does UBL-CR-397 mean? A UBL invoice should not include the DeliveryParty PartyLegalEntity

Why did my invoice fail UBL-CR-397?

The UBL element cac:Delivery/cac:DeliveryParty/cac:PartyLegalEntity should not be used in an EN 16931 invoice. Legal registration data is defined for seller and buyer only; the deliver-to party is limited to its name (BT-70) in the core model. Note that the deliver-to party name goes in cac:PartyName, not PartyLegalEntity.
