Enable Role Delegation for Line Manager

Hello,

We're trying to setup role delegation for our custom Line manager role. After clicking on "Delegation allowed" in the "Edit Data Role: Role Details", when I want to submit my modification, the following error message is displayed :

"You need to specify valid person security profile criteria for evaluating the manager hierarchy content because delegation is allowed for this role. (PER-1531594)

The referenced person security profile has a hierarchy content value that's inconsistent with the hierarchy content on this role definition. Either select another hierarchy content value or disable delegation for this role."

As I understand, either I need to setup a specific Person Security Profile for my Line Manager, either I can't enable delegation ?
