You can see your PO history shows 36018 for invoice posting. That's the reason you can see still to invoice as (325008-36018).
So you need to think think about the PO history, why does system update only 36018 amount for invoice posting ?
Can you please give us more details about your invoice posting. I can see some extra line items for your accounting entry, can you please explain it.
By the way, Amount (in ME2N) is too much bleary. (can't be seen at least by me)
