When my A/R person is applying  checks to customers and she hits auto apply she is not getting the credit balance. For example if customer XYZ sends a check for $500.00 and they have two invoices that equal $495.00 the customer should have a $5.00 credit on the account if the A/R person were to enter a check amount of $500.00 and hits auto apply. What is happening is the check total changes to  $495.00 covering both invoices but not adding the remaining $5.00 as a credit. Can anyone explain why this is happening and how to fix?
