How to hide individual input fields in contacts additional info in Redwood page?

We have a requirement to hide the tobacco use and the student status field to be hidden from the employees while creating/editing a contact and it should only be visible for the admins. To achieve this, we have created a global rule to hide these input fields and a role specific rule to show the fields for the admin with admin role, however it is not working. We were able to apply this logic to the entire Additional Information section but not to the individual fields. Could someone help us on this ?
