Memo disappears after using a credit in Receive Payments

Each time i use a customers credit in Receive Payments, when I return to the main window after applying the credit, to complete the payment, the Memo has disappeared with the information of who the payment is for.

I then either need to enter this manually if I notice it or close out of receive payments window and reopen after applying a credit and start again to receive the payment.

This also happens to me when Paying Bills.

I use a credit toward the payment and when finished using credits, return to the Bill payment window and the Memo has disappeared.

I fix this the same way as above, close out and go back in or enter manually.
