Hi @sabrina.refurbed,
I am happy to support you with your inquiry! 

I had a look into your request and this might be because the All employees role functions as the base for the Access rights, that’s why it is greyed out. If All employees role has the View and Propose rights for the Attendance data, the rest of the employee roles would have at least those rights. In order to change this, you will need to remove the View and Propose rights for All employees and then to create another Employee role for the rest of the employees who should have those rights. For that, you can navigate to Settings > People > Employee Roles > Create new role. Now, after removing the Access rights, you will be able to unmark the View and Propose rights for Own or even, not to see them. For more information about this topic, you can visit our Helpcenter article: Access Rights.

I hope this helps Sabrina! Please let me know if you need further information! 

I hope you have a good rest of the day!

Best,

Zulema
