Bitrix displays a footer from another site. urlrewrite error?

Question

Hello.

I'm trying to set up a new site in multisite mode. Sites on the nikastm.ru and sunduk-domovenka.ru domains work more or less correctly.
I am creating a new website on the vestdom.ru domain.
The footer (and other) sections display information from the site nikastm.ru.
But if I want to edit any element in edit mode, then /var/www/vestdom.ru/include/footer/contacts-title.php opens for me, although /var/www/nikastm.ru/include/footer/contacts- title.php

Tell me in which direction I should "dig".
