No access to change view permission for team members

No access to change view permission for team members

Hi, I want team members to be able to update the percentage progress on their goals at mid year. Currently they cannot edit this, they can only update the comments against the goals. The ability to add view permission to goal progress for team members is greyed out, and I cannot change the edit permission until this is updated. I have SuperAdmin access. I have tried a number of troubleshooting options using online support, none of them have worked. How do I get this system setting changed please? Thank you.
