Django-paypal invoice has already been paid

I'm using django-shop-paypal and when i want to checkout via paypal I get a message "invoice has already been paid". The plugin posts the order ID as unique-invoice-id like 17 or 18.

When I manually change the unique-invoice-id to something like 189674 in the form and post to Paypal the checkout will work correctly.

Does anyone know why a simple small unique number does not work?

Thanks

This would be because you have already got paid invoices with the same number (maybe with a different site or previous tests)

Either prefix the invoices numbers with a unique code or number to make the invoice number different, or log into paypal and allow duplicate invoice numbers to be paid.

My Account > Profile > Selling Preferences

Block payments Limit payments, add instructions and more. Click Update

Block accidental payments: You may prevent accidental payments by blocking duplicate invoice IDs No, allow multiple payments per invoice ID
