Instead of a 404 error, a 301 redirect?

Question

1C-Bitrix

Good afternoon, instead of 404 errors and showing the page, Bitrix redirects to a higher level:

site/catalog/fdjksnfdksjnfkjsd -> site/catalog (301)
site/dkfmskld -> site (301)
site/contacts/randomstring2______ -> site/contacts (301)

in htaccess:
ErrorDocument 404 /404.php
in 404.php:

include_once($_SERVER['DOCUMENT_ROOT'].'/bitrix/modules/main/include/urlrewrite.php');
CHTTP::SetStatus("404 Not Found");
@define("ERROR_404","Y");
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/header.php");
$APPLICATION->SetTitle("Страница не найдена");

init.php:
его не существует
urlrewrite.php (at root):

/bitrix/modules/main/include/urlrewrite.php:
Не существует
Where to look?, tell me please

Answer 1

init.php
urlrewrite.php
look most likely here

array(
    "CONDITION" => "#^/#",
    "RULE" => "",
    "ID" => "bitrix:catalog",
    "PATH" => "/catalog/index.php",
  ),
  array(
    "CONDITION" => "#^/#",
    "RULE" => "",
    "ID" => "bitrix:catalog",
    "PATH" => "/catalog_test1/index.php",
  ),

Most likely on the main one there are 2 CNC components, which are not required. What creates a rule that is possible and causes that page instead of 404
