Unable to void a payment

I applied a payment to a vendor via a credit card.  I voided the paymet on the credit as I paid $0.17 to much.

I also tried to void the payment in the vedor as it was opened and it will not let me void.  I receive the message document can't be marked for voiding as it is partially applied or there is a hold on it. 

How may I void the payment, with $0.17 credit now so I may enter the correct payment in the credit card?

Thank you
