Seller information viewable to other users in user profile

I want users to be able to view seller profiles for basic information and contact form, but when I enable the 'access user profiles' in permissions, a seller button becomes available on the user's profile for other users to see - see attached screen shot.
This button provides access to a sellers selling reports and other info that should be kept private.
How would be go about removing this button? Presumably it shouldn't be there?
