Wrong SSL on subdomains?

Question

Apache HTTP Server

There are 2 domains site1.ru and site2.ru both have ssl. I added the test.site2.ru subdomain, and a certificate from site1.ru was automatically connected to it.

config

site2.ru.conf:

<VirtualHost *:80>
        ServerAdmin [email protected]
        DocumentRoot /var/www/site2.ru/public_html
        ServerName site2.ru
        ServerAlias www.site2.ru
</VirtualHost>
<VirtualHost *:443>
        SSLEngine on
        SSLCertificateFile /etc/ssl/site2.ru/site2.ru.crt
        SSLCertificateKeyFile /etc/ssl/site2.ru/private.key
        SSLCertificateChainFile /etc/ssl/site2.ru/chain.crt

        ServerName site2.ru
        DocumentRoot /var/www/site2.ru/public_html
        DirectoryIndex index.php index.html
</VirtualHost>

<VirtualHost *:80>
        DocumentRoot /var/www/test.site2.ru/dist
        ServerName test.site2.ru
</VirtualHost>

site1.ru.conf: аналогичный конфиг, но со своими путями для ssl

It turns out that I need to disable the certificate for the test.site2.ru subdomain altogether. Tried adding a VirtualHost for the subdomain with SSLEngine off, however, that didn't work. And I can’t understand: why is the ssl of the site1.ru domain assigned to the test.site2.ru domain?
