You created a custom Security Role by cloning a default one, the "Symantec Level 2 Workers". This custom Security Role should only have access to certain menus, like the "Settings" menu for example. However, you don't want the "Manage" menu to be accessible / visible.
After granting and removing the proper Permissions and Privileges on what you want to be accessed in the SMP Console, you still see "Manage > Software Catalog" as a console menu
Even when it is not one of the selected items in Security Role Manager.

There were some inherited permissions coming from the "NT Authority\Authenticated Users" role.
In order to completely remove "Software Catalog" (even when it does not do anything when clicked), try the following:
