Problem with task delegating to subordinates

0

I try to use the following functionality:
"Security based on organization structure.

This functionality allows you to view and edit your subordinates’ instances and tasks (in the same manner that those subordinates would be able to),
and also lets you delegate subordinates' tasks to yourself (or another person), in order to take over and complete them. "

I can view and edit my subordinates' documents but I can't "delegate to another person".
