productscategory module - product limit fix? (PS 1.6)

[NoroHadzi]

Hello,

Im using original module productscategory on prestashop 1.6. I want to show 6 products, so i changed this line:

$category_products = $category->getProducts($this->context->language->id, 1, 6); /* 100 products max. */

Problem is, in some products I see only 5 products. 

I think the problem is becouse of deleting current product from the list... (when I delete this lines of code, i see in each product the right number - 6 products, but one is the same as current product):

// Remove current product from the list
            if (is_array($category_products) && count($category_products))
            {
                foreach ($category_products as $key => $category_product)
                {
                    if ($category_product['id_product'] == $id_product)
                    {
                        unset($category_products[$key]);
                        break;
                    }
                }

Does anybody have modification that works for selected number of products and not showing current product in list? Thanks
