SLA on Flow have items queued even case has been resolved
I have an SLA defined on a process flow, (Goal/Deadline set to 3 months from current date), but the case has been resolved and i would expect some sort of clean-up that happens internally to clean all the assignments (including the item created when process flow has started) but I can see SLA items in queue in "Scheduled" state, Why are these left? How can i clean these assignments. These instances are of "ASSIGN-INTERNAL XX-XXXXX-WORK XXX-0009-0410-1541-0001!PZINTERNALPROCESSFLOW"
