New HCM role which can view all data except Salary is conflicting with Line Manage Role

Summary:

Hi Everyone,

We have a request to create new HCM role which can view all data except Salary. While testing this role, we have assigned to a person who has custom Line Manager Role and it allows Line Managers to view all data including Salary for all persons. This should allow someone with directs to still have access via MSS, but prevents them from searching up salary in the core app. However, the new role is working fine if we assigned to person who doesn't have any roles.

Could any one please suggest, how to overcome this issue. Thank you!!
