Invoice is taking random existing supplier instead of the same supplier as per Invoice

Hi Everyone,

We are trying to interface an Invoice through IDR email and invoice is taking some random existing supplier instead of the same supplier that we have in Invoice.
We have created the supplier, Address and Site, contact based on the Invoice in the system and tried interfacing the Invoice through IDR but still it's taking random supplier and not the exact supplier that matching with Invoice.

Can anyone please assist me here?

Thanks in advance!
