Surcharge marked as not subject to VAT but seller has a VAT number

This is the rejection, word for word: „[BR-O-04] One of your document-level surcharges uses VAT category "O" (Not subject to VAT), but the seller has a VAT identification number. These contradict each other — if the surcharge is not subject to VAT, the seller should not have a VAT ID on this invoice.“
