Permalinks to sections/products in the Bitrix multilevel catalog?

Question

1C-Bitrix

There is a physical folder "/catalog" where the complex component is located in the index file.
Accepts parameters:

"SEF_FOLDER" => "/catalog/",
"SEF_URL_TEMPLATES" => array(
  "sections" => "",
  "section" => "#SECTION_CODE_PATH#/",
  "element" => "#SECTION_CODE_PATH#/#ELEMENT_CODE#/",
  "compare" => "compare/",
),
...

Structure:
Catalog (folder '/catalog')
-- {section1} ----
{section2} ------
{product}

• 
  
• /catalog/{section1}/
  
• /catalog/{section1}/{section2}/
  
• /catalog/{section1}/{section2}/{product}/
  

Don't let on links like

• 
  
• /catalog/{section2}/
  
• /catalog/{section1}/{product}/
  
• /catalog/{section2}/{product}/
  

My observations:
By the link /catalog/{section1}/{section2}/ I see links to the product in the following form:
/catalog/{section2}/{product}/
By the link /catalog/{section1}/:
/catalog/{ section1}/{product}/
By link /catalog/{section2}/:
Returns 404 status, while the page itself is displayed incorrectly. There in a cycle all existing sections get over.
The product is available through the following links:

• 
  
• /catalog/{section1}/{product}/
  (breadcrumb): Catalog > Section 1 > Product
  
• /catalog/{section2}/{product}/
  : Catalog > Section 1 > Section 2 > Product
  
• /catalog/{section1}/{section2}/{product}/ Breadcrumbs
  : Catalog > Section 1 > Section 2 > Product
  

Maybe some parameters need to be changed in the catalog.section call inside the complex catalog?
