Custom Select Query doubles posts

Custom Select query will SOMETIMES double the post. Meaning it’ll display the same post twice, consecutively. It only does it on certain term ids. Here’s the query

$querystr = "
			SELECT COUNT(ID)
			FROM $wpdb->posts
			LEFT JOIN $wpdb->postmeta AS date_value
				ON($wpdb->posts.ID = date_value.post_id
				AND date_value.meta_key = 'date_value')
	  		INNER JOIN  $wpdb->term_relationships
	              ON (wp_posts.ID = $wpdb->term_relationships.object_id)
	  		INNER JOIN  $wpdb->term_taxonomy
	              ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
	        INNER JOIN  $wpdb->terms
	              ON ($wpdb->term_taxonomy.term_id = $wpdb->terms.term_id)
			WHERE $wpdb->posts.post_status = 'publish'
				AND $wpdb->posts.post_type = 'custom_post'
				AND date_value.meta_value >= '" . date('Ymd') . "'
				AND $wpdb->terms.term_id IN ( $term->term_id )
	";
	$result = mysql_query($querystr) or die(mysql_error());
	// Print out result
	while($row = mysql_fetch_array($result)){
		$gs_count = $row['COUNT(ID)'];
	}
	unset($querystr);

I’ve only been able to fix this by deleting the post(s) and republishing them.
