Invoice subtotal doesn't match the line total

We found an invoice with one one line in Epicor. The subtotal of the invoice doesn’t match the line total. Why this happened? Anyone has this experience and know why, please help. Thanks.

Is this a built-in form or a customized form? A customized form you would have to get fixed through professional services. $$$

Otherwise maybe setup a test server with a newer patch and see if the issue goes away.

Also did you find this on the UI or in an SSRS Report such as Sales Analysis?

Thank you. We found it on both UI and SSRS form
