show all option wrong?

Hi almighty woo gurus! I got something that might be wrong or it might be right; On http://shop.bikeport.no/produktkategori/bremser/ I can see all 11 products in this category. But when I press “show all”, I get absolutely all products in the shop listed. I thought that this should list all products in this spesific category if you had more products than what fitted on the page?
