BI Admin role revokation not working

Summary:

Hello Everyone,

We have assigned a BI admin role to user and it worked fine. It has all the admin privileges. So far so good. We have realized that the user should not have BI admin role and we removed it from security console.

But even after removing the role from security console, The user still have admin privileges and he can do all admin related activities. Even we tried logging out multiple times but it did not work. We have removed all the roles ( user with no roles at all) but still the user has admin access in BI console.
