ZUGFeRD 2.0 xml is not valid

We tried to use the generation of electronic xml invoices with the format ZUGFeRD 2.0. Unfortunately, the xml files that are created are not valid. We get two errors regarding the “Buyer reference” and “SELLER CONTACT”:

val-sch.2.5 BR-DE-15 error [BR-DE-15] The element “Buyer reference” (BT-10) must be submitted.
Path: /rsm:CrossIndustryInvoice

val-sch.2.7 BR-DE-2 error [BR-DE-2] The group “SELLER CONTACT” (BG-6) must be submitted.
Path: /rsm:CrossIndustryInvoice/rsm:SupplyChainTradeTransaction[1]/ram:ApplicableHeaderTradeAgreement[1]/ram:SellerTradeParty[1]

Is there anything that we can do to add these information to the xml file?

Edit: An additional note: the validity checker that I use is a German one, as we need it for the German market. For the case that this is something only specified in Germany.
