It appears to be showing the last paid invoice as part of the total due even though it has been paid. So for example if I am emailing a reminder for a $25 invoice that is due it is also including the previous $295 invoice in the total due (even though the $295 invoice is paid). Once they click the Review and Pay link in the email they total due is correct. Most are not clicking this though they are instead seeing the larger total than emailing us as to why. This creates a lot more work for us and them.
