Hi,
You have another menu item with the alias "hikashop-menu-for-categories-listing". So you need to edit that other menu item if you want to change its alias.
By default, that menu item with the alias "hikashop-menu-for-categories-listing" is in the "HikaShop default menus" menu.
Also, if you change the alias "hikashop-menu-for-categories-listing" to something else and you have canonical URLs with "hikashop-menu-for-categories-listing" in them, it means you'll also have to change the canonical URLs.
And if you want the elements to use your "ptitsevodstvo" menu item instead of "hikashop-menu-for-categories-listing" while you have the "force canonical URLs on listings" setting activated, changing the alias of the menu item won't help. Instead you want to change the canonical URLs to use "ptitsevodstvo" instead of "hikashop-menu-for-categories-listing".
