Is the product feature vairiant image a bug?

I read this post: [url]http://forum.cs-cart.com/showthread.php?t=12988[/url]



I have tried this on the latest version of CS Cart:

create product feature variant and assign an images as well as a description to it. When I select the feature variant while creating a new product neither the image nor the description shows.



Is this a bug or can someone please explain what the point of this function is.
