Learning Journey has been deactivated, but why are learners still getting emails?

When a Learning Journey (LJ) is deactivated with a running course, it leaves the running blocks unaffected. It will remove all Pending training blocks, however if there is any block running it stays unaffected. 

Prior to clicking save when trying to deactivate LJ, below popup messages appears. 

This is the same behavior if you want to stop an individual course or the Learning Journey.
