Table columns do not display the alternatename fields properly if fullnamedisplay = 'alternatename'

It's found in Chinese language.
When the fullnamedisplay and alternatefullnamedisplay is set to 'alternatename', in the course management the display of "Browse list of users" is improper, that is, the display of alternatename field(别名) is lost. But in the site administation the display of alternatename field(别名) is normal.
