https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27435 --- Comment #3 from Holly <hc@interleaf.ie> --- I recreated this on master. I checked out three items to a patron in the "Patron" category. Two of these items were item type "Books". One of these items was item type "Visual Materials". The circulation rules for "Patron" and "Books" were: Fine grace period: 1 Suspensions in days: 2 Max. suspension duration: 10 Suspension charging interval: 1 The circulation rules for "Patron" and "Visual Materials" were: Fine grace period: 1 Suspensions in days: 1 Max. suspension duration: 10 Suspension charging interval: 1 The system preference CumulativeRestrictionPeriods was set to "Cumulate". When I checked the three items out on 15/01/21, I backdated the due date on the three items to 13/01/21. When I checked the items in together, all at once on the Patron Details page, the patron was suspended until 01/19/2021. I then checked the items out again and backdated them to be due on 13/01/21 again. When I checked the items back in, one at a time, under Circulation, Checkin the patron was suspended until 01/20/2021. -- You are receiving this mail because: You are watching all bug changes.
