Your config NEVER works for [ANOTHER-SITENAME].com, because http have redirect to https and https not working because SSL cert is only for [SITENAME].com.
If have two sites who use same files, make seperate blocks for them - it will be easier to manage and troubleshoot.
Make it simple, help yourself... For example:

[SITENAME].com

    server
    {
            listen 80;
            server_name www.[SITENAME].com [SITENAME].com;
            return 301 https://[SITENAME].com$request_uri;
    }
    server
    {
            listen 443 ssl;
            server_name www.[SITENAME];
            ssl_certificate /etc/letsencrypt/live/www.[SITENAME].com/fullchain.pem;
            ssl_certificate_key /etc/letsencrypt/live/www.[SITENAME].com/privkey.pem;
            return 301 https://[SITENAME].com$request_uri;
    }
    server
    {
            listen 443 ssl;
            server_name [SITENAME].com;
            root /var/www/[NAME]/latest;
            index index.php index.html index.htm index.nginx-debian.html;
            location / {
                    try_files $uri $uri/ =404;
            }
            location ~ \.php$ {
                    include snippets/fastcgi-php.conf;
                    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
            }
            location ~ /\.ht {
                    deny all;
            }
    }

[ANOTHER-SITENAME].com

    server
    {
            listen 80;
            server_name www.[ANOTHER-SITENAME].com [ANOTHER-SITENAME].com;
            return 301 https://[ANOTHER-SITENAME].com$request_uri;
    }
    server
    {
            listen 443 ssl;
            server_name www.[ANOTHER-SITENAME].com;
            ssl_certificate /etc/letsencrypt/live/www.[ANOTHER-SITENAME].com/fullchain.pem;
            ssl_certificate_key /etc/letsencrypt/live/www.[ANOTHER-SITENAME].com/privkey.pem;
            return 301 https://[ANOTHER-SITENAME].com$request_uri;
    }
    server
    {
            listen 443 ssl;
            server_name [ANOTHER-SITENAME].com;
            root /var/www/[NAME]/latest;
            index index.php index.html index.htm index.nginx-debian.html;               
            location / {
                    try_files $uri $uri/ =404;
            }
            location ~ \.php$ {
                    include snippets/fastcgi-php.conf;
                    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
            }
            location ~ /\.ht {
                    deny all;
            }
    }
