Unable to Delete PO (Purchase Order) due to changed Invoiced value. Helppp.

Question

If you create a service entry sheet, process the service entry
approval,post an invoice for an amount greater than the Service entry
then, cancel
the entry sheet and add a new service specification (i.e. same entry
sheet), the following problem occur:
1. You can no longer cancel the invoice if the services of the entry
sheet are deleted.
2. After changing the entry sheet and renewed acceptance of services
performed, a posting takes place where the value differs from the
value of the entry sheet.
Steps to Reproduce:
1. Create a Service Purchase Order of $2,000.00
2. Create a Service Entry against the Purchase Order for $2,000.00
3. Approve Service Entry against the Purchase Order for $2,000.00
a/c postings Dr Expense $2,000.00
                     Cr GR/IR $2,000.00
4. Create an Invoice against the Service Purchase Order for $5,000.00
a/c postings Dr Expense $3,000.00
                    Dr GR/IR $2,000.00
                    Cr Vendor $5,000.00
5. Revoke the Service Entry
a/c postings Dr GR/IR $5,000.00
                    Cr Expense $5,000.00
I am expecting the Reversal of the Service Entry figure is $2,000.00, but instead, the Reversal of the Service Entry figure is $5,000.00. Why is that so? I need to be able to Reverse/Delete the PO.
