nop 2.2/2.3: Payment method not available when price is 0

Hi

If I have a product that is free I get the error <Payment Method not Available> after confirming the order and the order is not completed. Is it the wrong way to proceed products that is free, my setup is wrong or is it a bug?
I´ve tried with following payment methods: Payments.CheckMoneyOrder, Payments.PayInStore and Payments.PurchaseOrder. All giving the same error. But works fine if ordertotal>0.

Log:

Log niveau: Warning
