paid the creditor more than the credit on his account

The situation is, I've made a purchase on 16/12/2016 for 2888.61 on the 19/12/2016 I've paid my supplier 2560.00 from my bank account (328.61 credit left in the supplier account) then on the 01/01/2017 I've made a cash payment to this supplier for 330.00 there was only one bill created for the amount of 2888.61 I've used that bill to pay 2560.00 but couldn't use it again for the 330.00 payment so I've created another bill for 330.00 although the trial balance is showing the right amount in creditors account it's showing the wrong amount in that supplier account. Please can you help me and tell me how to correct that? so the right amount its shown on my supplier account
