Please click on "collezioni" and from menu, look to "zecchino d'oro" (BRAND category) and its subcategory ("primavera estate","autunno inverno", "stagione corrente").
Clicking on "zecchino d'oro" now you can see I duplicate articles from subcategories to obtain right pagination for brand category.
That's not the solution, I know...
