Security Profile by AOR and Person Security Profile doesn't restrict people's access

Hello,

We have an Enterprise that has 5 legal entities/BUs with different HR personnel who shall have access each for their own Legal Employer only.

I've created Person Security Profile by Legal Employer and I've added it to the data role security profile to "Person" and "Public Person" section, but the employee who's got the role still has access to employees from other Legal Employers from "Person Management".

I've tried copying a seeded role and a role we already have for the HR to be copied with the other privileges.

I've tried with AOR in the Data Role Security Profile, after creating an AOR to the employee.
