I tried to put it in gallery.php, and functions.php, but suppose problem might lie here

<?php

add_filter( 'post_gallery', 'authentic_post_gallery', 10, 3 );

function authentic_post_gallery( $output = '', $atts, $instance ) {

  $post = get_post();

  $default = array(
    'id'         => $post ? $post->ID : 0,
    'order'      => 'ASC',
    'orderby'    => 'menu_order ID',
    'columns'    => 3,
    'size'       => 'thumbnail',
  );

  $atts = array_merge($default, $atts);

  $id = intval( $atts['id'] );

  if ( ! empty( $atts['include'] ) ) {
    $_attachments = get_posts( array( 'include' => $atts['include'], 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $atts['order'], 'orderby' => $atts['orderby'] ) );

    $attachments = array();
    foreach ( $_attachments as $key => $val ) {
      $attachments[$val->ID] = $_attachments[$key];
    }
  } elseif ( ! empty( $atts['exclude'] ) ) {
    $attachments = get_children( array( 'post_parent' => $id, 'exclude' => $atts['exclude'], 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $atts['order'], 'orderby' => $atts['orderby'] ) );
  } else {
    $attachments = get_children( array( 'post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $atts['order'], 'orderby' => $atts['orderby'] ) );
  }

  if ( empty( $attachments ) ) {
    return '';
  }

  $selector = "gallery-{$instance}";

  if (isset($atts['layout'])) {

    $layout = $atts['layout'];
