Deposit Reversed

Here's a scenario1) i have created a Deposit
2) Made receipt of the deposit
3) applied the deposit to an Invoice (as commitment)
4) reversed the deposit receipt
5) reversed the deposit invoice

BUT

The invoice from POINT3 is still showing. The commitment field on the invoice still has the deposit Invoice number visible

Q. How can i reverse the effect of the commitment from the Invoice (from POINT3)?
