Invoice match option with the receipt is not working for isupplier sourced invoices

Dear Team,

I have a question, we have supplier portal enabled and for a PO , the line type is 'Fixed Price Services' and the invoice match option is 'Receipt'.

The requester of the backing requisition of PO , has done the receipt for 10000 and later on corrected the receipt to 5000.

Now when the supplier is creating the invoice for the same PO , the supplier is allowed to create the invoice for 10000 which is incorrect.where as if go and check under the PO from supplier portal it is reflecting the right receipt amount in 'Fulfilment summery'
