Works for me when I switch to global admin, regional admin, and standard user.

When I am a global view user, it says "Regional Admin" . I'm assuming it should say "Global View User". @schmelz21 ?

@stewartl97 - In mobile (sm) mode are we satisfied with not displaying the UserType?

@schmelz21 Yes, we can revisit this later, but for this particular issue we can hold off on displaying usertype.
