Feature products module problem

[Stamos]

Well...iam trying to put this out but nothing:

In the product module, i set to display feature products, i have more than one feature products in my site, but the module always show the same product, its not random.

I think it should display other feature product every time i refresh the page, but not.

Its a bug? I dont think i have something wrong...i have checked it on many ways.
