Access to Offer Team in Job Offer limited visibility

Hi everyone,

during testing we discovered that some Security Groups can't see the whole Offer Team. Altough they have access to the quick action Manage Job Offer and have the necessary priviledges to view the Job Offer for a Candidate.

The Hiring Manager and the Recruiter is visible as read only for everyone. But whenever there is a additional Collaborator, no one except the Recruiter (who can also edit the Job Offer) can view the additional Collaborator.

In the image below, our Employee-Life-Cylce Admin can't see the Workers Council and the HR Business Partner Names. But however he can see the Hiring Manager and the Recruiter Names. We checked all Function Security Priviledges. We think it might be related to the Area of Responsibility, but can't figure out what exactly needs to be done.
