IDR Invoices - gross amount scanned at line level

Summary:

Content (required):

For a certain supplier, invoices were previously being correctly scanned with gross amount at header level, net item line and tax line.

Recently, AP team have reported that line level is being scanned with gross header amount and tax is therefore incorrectly calculated.

There has been no change to the structure of the supplier's invoice image and it is clear what the gross, net and VAT totals should be. Please see attached image (sensitive details redacted) and invoice created in the system.
