Duplicate content issue due to Codeigniter controllers - php

Question

I am assisting with a Codeigniter website and don't have a background with it. It has been noted that there is duplicate page content. When I dug in, they are not actual pages, but controllers pointing to the same views. I attempted to set up 301 redirects in an .htaccess file in the root of the website, but it is not taking. In the application/config/routes.php, the following is noted:
$route['default_controller'] = 'Home';
$route['404_override'] = 'Home';
For example, there is a page http://mywebsite.com/weddings, and then http://mywebsite.com/Home/weddings was another controller that pointed to the same view. I attempted to add a 301 redirect from Home/weddings after removing the additional controller pointing to it, but now Home/weddings just redirects to the home page, as it is set up with the 404 override. I hope I have provided enough information for some assistance.
.htaccess file:
RewriteEngine On
RewriteBase /
# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ $1/ [R=301,L]
# allow access to certain directories in webroot
RewriteCond $1
!^(index\.php|robots\.txt|css/|lib/|js/|images/|^(.*)/images)
# gets rid of index.php
RewriteRule ^(.*)$ index.php?/$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# page redirects
RedirectMatch 301 ^Home/weddings/$ /weddings
Home.php is as follows:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('Admin_model');
$this->load->model('Home_model');
$this->load->helper('captcha');
$this->load->library('recaptcha');
}
public function weddings()
{
$this->load->view('Template/Home/front_header');
$this->load->view('Home/weddings');
$this->load->view('Template/Home/front_footer');
}

Do not touch .htaccess. You have two options.
Create a controller Weddings.php and in your index.php return a
view for weddings page.
The other option is to use Home.php controller and then add weddings method, the method should return the weddings page view. Your route should look like below:
$route['default_controller'] = 'Home';
$route['404_override'] = 'Home';
$route['/weddings'] = 'home/weddings';
Hope this will help. Thank you
Edit
In your Weddings.php controller constructor check if there exist a "Home" and return 404 error. See below
function __construct()
{
parent::Controller();
if($this->uri->uri_segment(1) == 'Home') {
show_404();
}
}
