I have used the estimate-to-invoice feature for a long time.  I always create the estimate and then create an invoice for a percentage of the total for the customer to send their down payment.  I used to be able to go into the estimate and click create invoice and a box would come up asking if I wanted to bill another percentage or the remaining balance.  Now, when I click "create invoice," it only creates an invoice for the full amount of the estimate. I can see the first invoice is linked to the estimate and the first payment is linked to the invoice.  What has changed?  Why can't I create an invoice now for the remaining balance? Thank you!!
