Marking an Invoice "Paid"

[epretorious]

1. I manually generated a $0 order for a domain name for a client [Orders: Add New Order].
   
2. I accepted the order [Orders: List All Orders -> Accept Order], and then
   
3. I marked the order as paid [Billing: Invoices: Unpaid -> Mark Paid].

However:

 

• When I view the order [Orders: List All Orders]: The order status is Incomplete.
  
• When I view the client's orders [Clients -> <Client ID> -> Invoices]: The order status is Incomplete.
  
• When I attempt to add a payment to the order [Billing: Invoices: Unpaid -> <Invoice #> -> Add Payment], WHMCS warns...
   

  Invoice in Paid Status
  As this invoice is already marked paid, any further payments applied will result in a credit to the client

Why is the status of the invoice inconsistent when viewed through different modules (i.e., Clients, Orders, Billing)?

How can I make the status consistent?

I fixed the problem by disregarding the warning...

...and adding a $0 payment to the order [Billing: Invoices: Unpaid -> <Invoice #> -> Add Payment].
