New Font Filters

Quick question about the font filters. Forgive me if I am a bit of a Typeface/Font Noob. 

Is the full list of filters a Premium only feature? Or are my font files missing some kind of meta data that provide for the filter? I have tried rebuilding the database file, and I get the same result. The funny thing is, Bitstream can filter between Script/Serif/Sans Serif Typefaces without any problems.
