Display -> Content Menu missing

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5
-- PHP version -- : 5.3.10
-- Browser(s) name and version -- : Safari 6.2.8

I don't have the Display -> Content Menu and Content modules menus that I see in the demo. Also I couldn't mange to get the desired view for products of a sub-category of the main-category. I tried to create menu entries and modules but it didn't help. Sorry I'm new to Hikashop, but the connection between the modules and menu items are not clear yet. How to configure the display of products of a sub-category and why do I miss the above items?
