I don't have duplicated "overrides" but the only question is : how do you delete an "Override (task types)" folder in the "Manage tasks workflow schema" window ?
I can move tasks from the "Override (task types)" folder to put them back in "Task types (default)"... but how can I delete an "Override (task types)" folder once it's empty or not ? No "Remove override" button on screen (only the "Add override" one), no right-click contextual menu, no keyboard shortcut (I tried "del", "suppr"... etc). So ? Is it only possible ? Thank you.
