Issues went creating a payment with gift card (MPOS AX 2012 R3)

Hello, I tried to look for an answer on the forums but failed.

I've set up a gift card payment and I am able to issue it and so on. But when using it as a payment method and trying to use the giftcard it performs a partial payment, I cannot complete the sale in the POS after that, resulting in application error. Anyone encountered this type of issue when setting up any payment methods which create partial payments and then gets you stuck in the transaction?

Thanks in advance,
Mannan
