Why doesn't the menu see the $aMenuLinks array?

Question

1C-Bitrix

For two sites (multi-site on different domains), the top-type menu should contain different names of links and their values. But on the second site, the values ​​are the same as on the first site, although there is a separate $aMenuLinks array for it, located in the root of the site. What could be the reason? If you edit through the visual part, then the links on the first site also change.
The contents of the .top.menu.php file

<?
$aMenuLinks = Array(
  Array(
    "О нас", 
    "/about/", 
    Array(), 
    Array("icon"=>"fa-comments"), 
    "" 
  ),
  Array(
    "Контакты", 
    "/contacts/", 
    Array(), 
    Array("icon"=>"fa-file-o"), 
    "" 
  ),
  Array(
    "Доставка", 
    "/delivery/", 
    Array(), 
    Array("icon"=>"fa-clock-o"), 
    "" 
  )
);
?>

Menu:

<?$APPLICATION->IncludeComponent(
                        "bitrix:menu",
                        "big_horizontal_menu",
                        Array(
                            "ROOT_MENU_TYPE" => "top",
                            "MENU_CACHE_TYPE" => "N",
                            "MENU_CACHE_TIME" => "3600",
                            "MENU_CACHE_USE_GROUPS" => "Y",
                            "MENU_CACHE_GET_VARS" => array(),
                            "MAX_LEVEL" => "1",
                            "CHILD_MENU_TYPE" => "left",
                            "USE_EXT" => "N",
                            "DELAY" => "N",
                            "ALLOW_MULTI_SELECT" => "N"
                        ),
                        false
                    );?>

Thank you very much in advance.
