Problem with Email Confirmation since Update

I am suddenly seeing changed formatting of email confirmation for about a week now, and I think it probably is a result of this change reported in the changelog for version 5.6:

> Notification emails now show total to pay

Here is the problem — we do not use the form to sell items that related to quantities. It is simply a way for users to pay online from invoices that we send them — so it is a simple form with fields to enter their invoice number, amount of payment, and personal contact information.

In the past we would get emails formatted like this:

Order Details:
Invoice #: 1234

Quantity: 1

Enter Amount Paid: $100.00

The “Quantity” field was irrelevant and unnecessary, but wasn’t confusing.

But now here is what we are seeing:

Order Details:
Invoice #: 1235

Quantity: 1 @ $100 each

Total: $0.00

So this is very confusing, because even though the person has paid the full amount (example: $100) – we get an email that says “Total: $0.00”. Also, I do not know what users are seeing in confirmation mails — so far, no complaints, but if the user confirmation is the same as what we are receiving, then it also going to cause confusion.

So basically — we’d like to get rid of display of the “Quantity” field altogether — as it is not a field included within our form—- but if that can’t be modified, then at least the “Total” should be correct. If it is “Quantity: 1 @ $100 each” then it should also display, “Total: $100.00”)
