Loop on a wordpress Page instead of content coming from the WP text editor

On your custom page template, the default loop is working and that’s why the loop is fetching content from the page. You need a custom query in this case. Here’s the code.

<?php
$query = new WP_Query( array(
    'post_type' => 'post',
    'post_status' => 'publish',
) );
if ( $query->have_posts() ) {
    while ( $query->have_posts() ) {
        $query->the_post();
        get_template_part( 'content', 'home' ); 
    }
}
