What it means
When the seller has a tax representative (BG-11), someone appointed to deal with VAT on the seller's behalf, the tax representative name (BT-62) may appear only once. The rule counts the names inside the tax representative party and fails when there are two or more.
Why it matters
The invoice has room for one tax representative name.
How to fix it
Open the tax representative details in your invoicing software and check that the name is a single entry. Remove the extra one and export again. If you build the XML yourself, cac:TaxRepresentativeParty may contain at most one cac:PartyName/cbc:Name.
