[Koha] renewal period setting

Dear all, please help me to set the renewal period in circulation and fine setting . as our library users can renew the book 3 times and the renewal period is 10 days. But when I try to renew a book it only renews 1 day at a time. If the due date is 22June 2021 then if i renew it gives 23 June 2021. According to our rule it should be 01 July 2021. Please help me out Thank you in advance Nalisha Tamang Rai
