Payable Invoice accounting going to non recoverable tax/vat instead of recoverable tax/vat account

Summary

Payable Invoice accounting going to non recoverable tax when it should be going to recoverable tax

Content

For some reason payable invoices (non po and po matched invoice) are being accounted and the accounting generates a non recoverable tax line when we are expecting invoice to be accounted and to generate a recoverable tax line. This is happening sometimes but not all the times.

This seems to be happening randomly and for both non po and po matched transactions. I do not believe there is any way in Payable Fusion screen that you can amend the invoice so it generates a non recoverable tax line which has the same GL code combination as the item line? Does anyone know as it looks like user error but we cannot understand how you can alter the invoice so that when it accounts, the system create a non recoverable tax line when it create a  recoverable tax line and post to the Recoverable GL Tax account ?
