Export - Invoices - Customer invoices and payments - Payment method

Hello together,
Maybe I don’t understand something so precisely when exporting, or some mistake spirits around in the export.

I want to export a list of the following content:

Invoice date
Invoice number
Payment Method (Label)

I tried this with the export filter customer invoices and payments.

Invoice date and invoice number are no problem.
No data is exported in case of payment mismatch. Of course, all invoices have a specified payment method.
Is it only exported if these are stored in the data of the business partners?
This would be quite unfavourable, since you can choose the payment method again for each invoice.
