Sage Automatically Created Credit Memo - How Do I apply it to a customer invoice

Hello

To explain the situation. Someone created an invoice in error to receive a deposit from a customer (should have just received the deposit and not created the first invoice). I found that they had created this Invoice in error so I reversed the invoice. When I reversed it Sage 50 automatically created a credit memo . I cannot access the credit memo at all, it just say cannot find data. But when I go to print a statement the credit memo shows up. How do I apply this credit memo that automatically was created to a specific outstanding invoice (that it should have been applied to, to begin with)?
