Store sidebar "arrange by price" feature not working

I'm using your shop-combination-filter.html template to create my affiliate offers page.
I have every JavaScript file added to my page what you also have on your demo pages.
However, the ordering by price features don't work for my page.
I'm using this sidebar code:

					
						

							

								Select Category
								
									
- [Clear](#)
									
- [Non-fiction](#)
									
- [Fiction](#)
								

							

							

								Sort By
								
									
- [Clear](#)
									
- [Name](#)
									
- [Price: Low to High](#)
									
- [Price: High to Low](#)
								

							

						
					

As you may notice, this "Sort By" section is an exact copy of your demo code, which works perfectly on the template I've downloaded after purchase.
This is an item the feature is supposed to be able to sort by price:

Please let me know if you have any idea what can prevent this feature from working properly.
Thank you.
