How to display detailed news with multi-site?

Question

1C-Bitrix

Hello. There are two sites, one site.ru, the second en.site.ru/en/. Both are in the admin panel and the information for them is displayed correctly. The template for them is the same. The folder for the first is in the root, for the second - /en/
But there is a problem with displaying detailed news on the second site: it redirects to /bitrix/urlrewrite.php after the site is transferred to a new domain.
urlrewrite.php is in the root, and is in /en/, and the rules are the same in them, and this is most likely not supposed to be. But even when editing - nothing changes.
I haven't come across anything like this before, so I'm asking for help.
