Bitrix how to remove an element from the menu that is not in it??

Question

PHP

There is a menu on the site
and the "about us" section is duplicated here,
so in the "menu management" it is not there at all T_T
and there is no page with this address either (I already tried to create it, and then delete it with the "delete from the menu" checkbox - nothing happens )
The template should not have ... since there is nothing there rules.
Give me an idea what it could be?
and menu code:

<?
$aMenuLinks = Array(
  Array(
    "Мы предлагаем", 
    "/our-offers/", 
    Array(), 
    Array(), 
    "" 
  ),
  Array(
    "Каталог", 
    "/catalog/", 
    Array(), 
    Array(), 
    "" 
  ),
  Array(
    "Цены", 
    "/price/", 
    Array(), 
    Array(), 
    "" 
  ),
  Array(
    "О нас", 
    "/company/", 
    Array(), 
    Array(), 
    "" 
  ),
  Array(
    "Контакты", 
    "/contacts/", 
    Array(), 
    Array(), 
    "" 
  )
);
?>

Look for the .memu.ext.php file, it may be there, the file may be in the root or in the about us folder
