Category displayed incorrectly if alias not unique

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.0
-- Error-message(debug-mod must be tuned on) -- : None, wrong content displayed.

We have two category branches, some of the category names are identical. Hikashop generates the alias automatically, but does not check, if the alias is unique (in your case: woman - shoes and men - shoes).

I turned off the category number in the links. Since the tree is not part of the url (which is good), now multiple categories have the same link (../category/shoes) and system displays incorrect content.

Alias needs to be unique. Automatic checking should be done, at least if category numbers are turned off.
