[Koha] The patron has a debt of $5.00

Dear friends, I encountered a problem while circulation process with Koha. We use Koha 2.9 with Fedora 3. When clicking on issue button after enter barcode, a message shows as follows, “Please Confirm Issue: The patron has a debt of $5.00” I earlier implemented rent and fines. Recently I removed rental charges and fine in item types and issuing rules. Request your help to solve this problem, Vimal Kumar Asst.
