Static F Page: Duplicate Content?

I have a static font page https://esenciahispana.com and WP at https://esenciahispana.com/esencia/ – I include the header in my index.php (in root):

<?php
define(‘WP_USE_THEMES’, false);
require(‘./esencia/wp-blog-header.php’);
get_header();
?>

This shows my front page’s Meta Tags (title and keywords) as same as the page that I define as main in the blog (/nosotros).

I want to know if I can to change it or if this is not a worry for google and friends.

Thank you!
