If a client has new charges, plus they had a previous invoice which they paid, when invoices are printed, the check is showing up on the invoice but it does not say "Previous Balance" so it's very confusing for the client because they think the check is being applied to the current charges. And I've gone into my template and the "Previous Balance" check box is checked. What's weird is it doesn't happen on all the invoices. And all the invoices and payments have been approved so that can't be the problem either. The client where it's working and the client where it's not working are using the same template.
