I tried various purge options under Site Settings > Nintex Workflows > Manage Work History List
to delete the history for Cancelled Workflow. I even delete through today. I expected these critters not to show when I went to view Workflow History.
The workflow history of my cancelled workflows remained accessible after I ran the purge.
I, even, deleted all items and they still remained. How do you clean up and purge these beasts?
thanks,
Stephan
