Single View does not respect User Policies settings

The Single View of the Grade book does not respect the User Policy fullnamedisplay or alternativefullnameformat settings. No matter what is set, the Single View displays "First Name (Alternative Name) Last Name" or "First Name (Alternative Name) Surname"

If "firstname lastname" is set as the fullname display, then one would expect this to be the case in the Single View as well. 

This can be seen on the Moodle Demo site as well:
