Showing products from category on website homepage

-- url of the page with the problem -- : localhost
-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3
-- PHP version -- : 5.5.12

Hi,

I'm trying to show products from one Hikashop category on my homepage.
Let's say I have category "Test".
I have this category assigned to Joomla menu position with the same name and alias as Hikashop category name and alias.

If I have in backend Display->Content modules->my module: Menu = none and Synchronize with currently displayed item when possible = yes, then product urls in my homepage module looks like this: example.com/component/hikashop/product/test
If Synchronize with currently displayed item when possible = No, then no products are appearing in my module on homepage.
If Display->Content modules->my module: Menu = Test (joomla assigned menu) and Synchronize with currently displayed item when possible = yes, only then products are showing and urls are displaying more-less as wanted: example.com/category-alias/product/test

The thing is: why do I have to assign joomla menu with Hikashop category in two places? Why it's not handled inside joomla menu position options like many other components have? Don't you think there're too many steps for doing it?

1) I need to cerate joomla menu position (Hikashop -> categoy listings type)
2) I need to go to Hikashop Display->Content menu->my menu (which I just created)
3) I need to select "Associated category"
4) I need to select "Menu" which I created at beginning

Wouldn't this be easier if while creating joomla menu position just select hikashop category? I'm new to Hikashop, so maybe there's some hidden purpose of having it the way it is now

Best regards,
Chris
