Pcard Regular voucher

 Hi All,

I am facing one problem here and its worked differently in production. I don't know how this is happened. 

Here is the scenario, 

I imported the Pcard statement file and loaded. Prepaid voucher got created of entire file and voucher posted ,paid to bank. Amount $ 500. - 

Couple of days after user approved the transaction and ran the voucher load stage  , voucher build process. Regular Voucher got created with the transaction amount of $100.

Problem here is regular voucher $100 also paid to bank. It shouldn't be. 

When regular voucher create , it should adjust to the prepaid voucher and not to be paid.  Any one knows what could be the problem. Any one has this faced the problem.
