Switcher disapears in attachment page

My polylang switcher disapears from navbar in attachment page. In other pages it works flawlessly. I am adding a switcher to navbar by using a filter in functions.php class. My attachment page code looks as simple is this:

<?php
/**
 * The attachment page.
 */

 get_header(); ?>
<div class="container custom-content">
    <div class="row">
        <div class="col-lg-6 col-sm-6 col-md-6 col-xs-12">

            <?php 

            $image_attributes = wp_get_attachment_image_src( get_the_ID(), 'full' ); // returns an array
            if( $image_attributes ) {
            ?>
            <img class="img-responsive custom-image-shadow" src="<?php echo $image_attributes[0]; ?>" >
            <?php } ?>

        </div>
        <div class="col-lg-4 col-sm-5 col-md-5 col-xs-12 col-sm-offset-1 col-md-offset-1 col-lg-offset-1">

            <?php $attachment_meta = wp_get_attachment(get_the_ID()); ?>
            <?php echo $attachment_meta['description']; ?> </br>

        </div>

    </div>
</div>
<?php get_footer(); ?>
