How to View Voices stored in a commercial style

[Luc]

Hi, Does anyone know how can I view the above.
Every time I try to view one of these voices (through Style creator or through the mixer), the main screen always ends up showing me my user voice folder.
I've unlocked the style and still no change.
The voice used in the style is not a "standard" voice for my keyboard (a sx920) so I'm assuming that it's stored in the style file itself.
Thank you for any insights into this.
