Hello,
Can you try to update your HikaShop in order to have both the same version, but note that the Grid/list system can only works on Item Menu (product/category listing), in module the system can't, so in order to achieved what you need you have to replace your module for an Item Menu (Menus => Main Menu).
And last point, you have to 2 place when you can actived the Table Switcher
1. in Main HikaShop Configuration => Display tab => Default parameters for DIVs part
2. In Item Menu listing itself, Menus => Main Menu, in your Item Menu, Products/Categories Options and Items part
Hope this will help you to move forward on your subject.
Regards
