Semi manual bank rec - negative AP entries

In 9.2, image 17. I have manually recorded an AP payment.  When I go into the semi rec, the system transaction is showing the voucher as negative, therefore it won't match off with the bank transaction, which is positive.

In 9.0, our current system, the AP entry comes through as positive (and can be matched off with the positive bank transaction).

Can someone please let me know how I can change the system so that it sends through the manual AP payment as a positive number to the semi-rec?

Thanks

Andrew
