Discount on Manufacturer does not show

Set up a new discount 10%
In category selected a manufacturer.
The products for that manufacturer show full price.

If the category is changed to all products for testing, all products display a discounted value.

Hi,

I'll need more information regarding your problem, so can you show :
- How did you configured your discount
- How did you configured your product
through some screenshots, and finally give me a link to that product page ?

Thanks .
