hikashop breadcrumbs not working correctly

In my store I have a main menu item named "bedroom" consisting of three submenus. The "bedroom" menu is associated to a category also named "bedroom" and its submenus are also associated to subcategories of "bedroom" category, accordingly.
When I am in the bedroom menu and click its submenu (named light), the breadcrumb and url will be correctly in the following way:

home->bedroom->light
index.php?option=com_hikashop&ctrl=category&task=listing&cid=38&name=light&Itemid=145

But the problem occurs when I move back in the breadcrumb. For example when I am at a product page named CrystalBulb and want to move back to the previous menu "light" , all the products will be shown and not just the related products for that menu!

Scenario:

The breadcrumb at product page is:

home->bedroom->light->CrystalBulb

I click "light" menu to move back. The breadcrumb and url will change this way:
home->bedroom->light
index.php?option=com_hikashop&view=product&layout=listing&Itemid=145

As you see the cid in the above url does not exist !! This results in all the products be shown and not just the products related to "light" menu.
Please help me with this issue.
