I fixed the issue myself.
What i was doing wrong was the query_posts line i had read
query_posts( array( 'post_author' => $current_user->ID,'post_status' => 'publish' , 'post_type' => array( 'user_lists' ) ) );
And the correct way should be
query_posts( array( 'author' => $current_user->ID,'post_status' => 'publish' , 'post_type' => array( 'user_lists' ) ) );
