On Pinpad, invalid SKUs count also displayed which is not same as POS screen.Any idea why there is n

When few valid SKU's and invalid SKU's are scanned. On the POS screen the invalid SKU message comes and only the valid SKU's are shown but on the pinpad both invalid and valid SKU count is shown thus confusing the user.

ORPOS version : 14.1.2

Can someone help to resolve this?

Thanks & Regards,
