I first recorded a Charge, then a partial Payment as a Receive Payment. Then, I created an Invoice which I was hoping would show the Charge, Payment, and Balance Due. It did not show the Payment. I even tried to go back to the Payment and apply it to the Invoice. I also tried to change the Dates.

Here's the Customer screen:

Here's the Invoice Template.

Then, when I want to send the Invoice to the Customer, it does NOT show any Payment Received.
