Vendor Transactions Listing with amount that already reversed

Hi

From the report below, there is a balance of (718) at total of Transactions Amount column but but this vendor is zero outstanding.
The amount (718) actually is from the PI transactions under batch 89-16 which already reversed via Bank Services.

Should the reversed transaction still show in this reports? or it should not included if it already reversed.  So there will be no balance at the Transactions Amount column.

It look confuse to me. Why it still show amount at Vendor total if it already zero with no outstanding.

Does anyone can explain the purpose to show the total at the transactions amount?
