Supplier Ledger report does not match Aged Payables Report

[Jen281]

We are using MYOB Premier (multicurrency) and are having an issue with the Supplier Ledger Report for one of our suppliers reporting an active balance however the aged payables report for the supplier has a nil balance. Refer to the attached redacted reports.

It is in relation to a supplier who pays in USD and the active balance showing appears to be in relation to gain/ losses on forieign currency when the invoices are paid. 

Could you please confirm if this is normal/ supposed to present this way in MYOB?

If so, we are unsure what the purpose of this showing as active in the supplier ledger would be.

Please confirm if there is a way to remove the active balance so it does not appear on the reports.
