There should be an org level preference under change management something like "allow automatic ecn creation"

The Check Box propagate behavior is hard coded within this specific workflow Task.
There is a site preference in change management for "Localized Create New Change Notice Task Name", since if the name changes, the behavior dissapears,
You must either keep the OOTB name for task as "Create New Change Notice", or use the preference to make this functionality run.
