featured product

Hello

First thank you for plugin , it working fine.
I have small issue with this plugin,
I want to show “featured product” randomly on main page, I use :
[featured_products per_page=”9″ columns=”3″ orderby=”rand” order=”rand”]
It working fine if the plugin is disable,
But when plugin work , it take over and change the sorting setting to the same as the plugin set (it set form _stock).
How can I solved it ?
Thank you
