Dear community We are using Koha 22.11.07. In our Koha circulation rule patron category have maximum 5 time renewal allowed (Renewal Count) with time period of 10 days (Renewal period). In administration menu *Renewal Period Base* is calculated based on old due date of book and for late return every day 1 rupee is calculated as fine. A patron have overdue of a book which is not returned till date with 30 days late, his account shows accruing fine of 30 rupees. when the staff renew the book, along with 30 rupees an amount of 20 rupees creating with a total of 50 rupees. If again renew the book it again generating an amount 10 rupees along with 50 rupees with total of 60. Since the account have already fine till the date why Koha generating fine again based on new due date of renewal. is it a bug or any configuration need to change?
