Languages get mixed on wp_query [ Polylang ]

Hi there,

I’m facing a mix of content on a wp_query.

I’m using the plugin Polylang with two languages.

Here is the code I’m working on :

<?php

  global $wp_query;
  $exclude = $wp_query->post->ID;

  $cat_ID = get_the_category($post->ID);
  $post_cat = $cat_ID[0]->cat_ID;

  $args = array(
	'cat' => - $post_cat,
	'posts_per_page' => 2,
	'orderby' => 'rand'
  );
  $your_query = new WP_Query( $args );

  /* loop */
  echo '<ul>';
  while( $your_query->have_posts() ) : $your_query->the_post();
  if( $exclude != get_the_ID() ) {
	echo '<li><a href="' . get_permalink() . '">' . get_the_excerpt() . '</a></li>';
	}
  endwhile;
  echo '</ul>';

?>

OR but same issue :

<?php
  $post_id = get_the_ID();
  $category = get_the_category();
  $post_cat = '-'.$category[0]->cat_ID ; 

  $args = array(
	 'cat' => $post_cat,
	 'orderby' => 'rand',
	 'posts_per_page' => 2,
	 'post__not_in' => array( $post_id )
  );

  $rand_query = new WP_Query( $args );
  echo '<ul>';
  while ( $rand_query->have_posts() ) : $rand_query->the_post();
	  echo '<li><a href="'.get_permalink().'" title="'.the_title('','',false).'">';
	  echo get_the_excerpt();
	  echo '</a></li>';
  endwhile;
  echo '</ul>';
?>

The current post is exclude on the display posts. But, on the two posts, the both languages are coming up.

In the same time, I want to exclude the category of the current post which is not working neither.

Any though to fix that is welcome.

Thanks a lot
