Oracle Cloud is not creating invoice for Correct supplier when scanned via IDR

When Non-PO invoice is scanned via IDR, we are seeing two cases:

1. The supplier name is not selected correctly. It is picking the Bill To name and creating the invoice for in the name of the entity itself, instead of picking the vendor name from the Ship To field on Invoice.
2. For one another supplier invoice, the supplier name is not present and logo of the supplier is present. In this case also the invoice gets created for a random supplier and without any lines.
3. If there is minor change in the supplier's name, can IDR be trained to read it as the name vendor name mentioned in system instead of what is mentioned in Invoice, eg - If the vendor invoice mentions Ship From as ABC and we have a supplier as ABC Corp, can IDR be trained to read ABC as ABC Corp?
