Okay, I got it. I unselected that module. Now the module below the products is gone, thank you.
However, when I click on each submenu item, dissapears again the left column categories module and any product show up, even thought I did the following:
1- I was checking up the Hickashop demo settings
2- I set the same settings from "Category Listing" to my "Productos" menu
3- I set the same settings from "Categories of Products" to my "Categories" module. The only thing differente is the "Menu" option, yours has "Category Listing Module" under "Hikashop Hidden Menus" in mine I don't have that, and I have chosen "Categories Listing" under "Hickashop Default Menus".
If I have copied the same settings, why is not working?... I almost give up 
Edited:
I asociated a module in that option, because of this:

In fact, if I click on subcategories image, I can't load any product right now
