Salary basis visible for another country - how to correct that ?

Summary:

Hello,  

We have tried to have our Legal Entity in the UK (LE UK) for whom the employees must be paid in pounds, and are attached for payroll to the Legislative data group for France and the UK named FR_UK Legislative Data Group. The Payroll statutory is LE France.

The issue is that HR administrators in France can see the UK Salary Basis, but we need them to not be able to see the UK Salary Basis, and vice-versa.

Could you help us solve the issue, we must make sure that HR users cannot see the salary basis that is set for another country (here France and UK).
