Total amount due confusing to customers when 50% deposit not met

We would like to be able to remove the option of showing the amount needed to reach the 50% deposit on customer invoices. It is confusing and aggravation to customers when the have a bill for $1,008 and we take payment of $500 they then receive an email stating the amount due is $4. Employees know the $4 means the amount to get to a full 50% deposit but many customers don't understand and some really believe that they only owe $4 and not $508. See booking RHTN-070123 for most recent issue. This inhibits our choice of how to do business and creates unnecessary frustration on the customers and employees. If you could just make the invoice show full amount due and NOT amount to get to 50% that would be great.
