Marketpress small issues with Excerpt

Hi

I am running marketpress at

http://gshock.tradr.com/compare/

Excerpt info not passing to shortcode call

In wpmu wpadmin in the main site I am entering product excerpt info.

Then when I run the shortcode at the gshock site

[mp_list_global_products tag="g100-1bv" text="excerpt" show_thumbnail="0"]

It only passes the title, featured image and buy link.

Can the excerpt be passed with the text="excerpt" code? or am i meant to create a custom css?

Cheers

Johnny
