As I understand it the "Advanced" list is correct - it is the one that the application itself is enforcing (if you uncheck an option there, the application will not use the specified certificate for that purpose). The list of purposes under "view" is, I believe, the list of purposes declared by the certificate itself, as specified by whoever generated the certificate. You may choose to use it for a smaller list of purposes, which is what Chrome is doing wrt email (in the same way, Firefox only trusts the CNNIC cert for SSL, not for email or binary signing).
How do you know?
