Pagination Issues

Hi i have a problem with the pagination, it’s displaying when shouldn’t, for example post per page:6, posts:3 = pagination is visible (image)
I’m using a custom template, and custom archive.php and search.php, the code is like

(POSTS LOOP)
wp_numeric_pagination();

------
functions.php

function wp_numeric_pagination() {
    global $wp_query;

    $big = 999999999;
    $tag = '<div class="pagination">' . PHP_EOL;
    $tag .= paginate_links( array(
            'base'              => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
            'format'            => '?paged=%#%',
            'current'           => max( 1, get_query_var('paged') ),
            'total'             => $wp_query->max_num_pages,
            'prev_next'         => True,
            'prev_text'         => __('<'),
            'next_text'         => __('>'),
        ) ) . PHP_EOL;
    $tag .= '</div>' . PHP_EOL;
    echo $tag;
}

I don’t think is a problem with my code, im using it for months on a lot of themes, including twenty fifteen and works perfectly, the paginations gets displayed only when are more than 6 posts per page.
