Why is my Apache VirtualHost directing to the wrong VirtualHost?

On an existing wordpress-installed droplet, I am installing a new wordpress instance (two wordpress installs in same droplet).

To do so, I followed the answer by ryanpq on this thread: https://www.digitalocean.com/community/questions/is-it-possible-to-install-another-wordpress-on-droplet

Similar to the commenters on that thread, my newer site redirects to my existing site (even after changing the DocumentRoot and Directory appropriately).

Here are my configs:

Within /etc/apache2/sites-enabled, I have 4 files: 000-default-le-ssl.conf 000-default.conf example1.conf example2.conf
000-default.conf and example1.conf` are copies.

example1.conf looks like so:

# Added to mitigate CVE-2017-8295 vulnerability
UseCanonicalName On

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        
        ServerName example1.io
        ServerAlias www.example1.io
        
        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options FollowSymLinks
            AllowOverride None
            Require all granted
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =www.example1.io [OR]
RewriteCond %{SERVER_NAME} =example1.io
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

example2.conf looks like so:

<VirtualHost *:80>
        ServerAdmin webmaster@example2.com
        
        ServerName example2.com
        ServerAlias www.example2.com
        
        DocumentRoot /var/www/example2

        <Directory /var/www/example2/>
            Options FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

my directory structure looks like /var/www/html and /var/www/example2

Within the control panel of my DO account, I created a new project for my newly acquired domain name.
I created new A and CNAME records. The A record points to the IP address of the older, existing, site (so, example2.com directs to 128…)

Additional: I noticed while following the user ryanpq’s answer, that the wordpress install I did only had a wp-config-sample.php, so I copied that file, named it wp-config.php and filled it in with the database info.

What am I missing?
