How to make bx-next, bx-prev (bx-controls direction) workable?

[CLance]

Hi. Referring page: http://www.denmall.com/index.php?id_product=119&controller=product

Version: 1.6.0.5.

 

 

In the module of ProductsCategory: "28 other products in the same category",

when the products is more than 5, user is allowed to click the arrow to roll to right, to look more products.

 

However in the module of ProductsSupplier (customised from ProductsCategory module): "17 other products in the same supplier",

there are no arrow to be click.

 

Does anyone know how to alter the code so that this module are workable in bx-controls-direction rolling and display products in only one row?

 

 

 

 

 

 

 

In my opinion, not the module css problem, because when I have only ProductsSupplier module in the product page, the bx-controls direction works as usual.
