Pending Clean Up
On a Nintex Workflow that has a "Conditional start" setting enabled, when trying to to switch setting back to manual start and republishing, upon openning the workflow, the option reverts back to "Conditional start" setting.
RESOLUTION1. Try to change the workflow settings while logged in as the site collection administrator.
2. Export the workflow, then import it with a different name and try to change the settings again and confirm saved changes.
