To recreate: - have or create a 2 or more waiting holds with expirationdates in the past - go to /koha/circ/waitingreserves.pl - select the "Holds waiting past their expiration date" - select 1 of your two holds and click "Cancel selected" - Koha gives you a confirmation modal and asks for a cancellation reason. That's good! - click Cancel All - Koha cancels remaining holds without a confirmation modal or asking for a reason. That's bad!
