The problem with multisite on subdomains, what could be the problem?

Question

1C-Bitrix

Again, confusion with this multisite.
I did this: I
created a second site in the admin panel with the name eng.domen.ru, there is also a site domen.ru
in the settings, everything is like according to the guides, the first one is registered as www.domen.ru the second eng.domen.ru sorting everything.
launched the wizard, chose a solution, installation completed, a lot of menu items came from the first site
by infoblocks looked everything is OK, for example: there is an infoblock "contacts", next to it is the same "contact" one is tied to S1 the second to S2
but info is displayed from the first site, for example, there is menu 1, it should not have menu sub-items from the first site, but they are, and if you open them, they open on this domain.
but this information is not displayed.
the first site is in the folder ../site/
the second site is in the ../site/eng/ folder
(or maybe there is a problem that the second site should not be in the folder of one site ?!)
I don’t know what to do anymore .. + before each info block there should be s1 or s2 for me 2 infoblocks with the same names, if you only look inside, then there are settings.
