Removed Task is still visible in Employee Journey

Hi Team,

We have removed some of the tasks from the checklist, but before removing the tasks from the checklist, the perticilar checklist has already been assigned to some of the employees. If there is any way to do that, we can still have the control to remove the deleted tasks under the check-in employee journey.

And also, removed tasks are getting errors when the employee tries to complete those tasks, attached to the screen.

Please let us know if it is possible to modify this error test massege.
