I make an order on the website and see the payment transaction ID=PAY00064 on the sales order:

I deliver the order and create an invoice.

The payment transaction is found in the short cut button on the invoice.

It confirms the right payment transaction=PAY00064

But when I push the pay button to register the payment, I get a totally different payment ID=PAY00065

How Can I register the correct payment ID which should be PAY00064?

I don’t have this issue if I activate automatic invoicing but I cannot have that since I might have to edit the sales order before by adding free stuff and add serial/lot number.
