If the image of the purchase invoice does not appear, try opening it with the Open original attachments button. You can view the image of the invoice here and check the invoice details, and when the invoice is transferred to the Purchase Invoices workflow side, the image of the invoice will be displayed correctly there.
You can also create a new PDF from the opened image using the Print to pdf function. After this, you can send the reformatted PDF for interpretation of the purchase invoices.
