Hi,
In the latest version, we have removed this part of DW Focus: News Slider widget. If you want display the "Show the category info", you can replace all the line codes in the dw-focus-slider.php file with the following code:

<?php  
/**
 * dw_focus_top_posts widget class
 */
class dw_focus_top_posts extends WP_Widget {

    function __construct() {
        $widget_ops = array('classname' => 'dw_focus_top_posts news-slider', 'description' => __( 'Display News as a Slider', 'dw_focus' ) );
        parent::__construct('dw_focus_news_slider', __( 'DW Focus: News Slider', 'dw_focus' ), $widget_ops);
        $this->alt_option_name = 'widget_recent_entries';

        add_action( 'save_post', array(&$this, 'flush_widget_cache') );
        add_action( 'deleted_post', array(&$this, 'flush_widget_cache') );
        add_action( 'switch_theme', array(&$this, 'flush_widget_cache') );
    }

    function widget($args, $instance) {
        $cache = wp_cache_get('widget_dw_focus_recent_posts', 'widget');

        if ( !is_array($cache) )
            $cache = array();

        if ( ! isset( $args['widget_id'] ) )
            $args['widget_id'] = $this->id;

        if ( isset( $cache[ $args['widget_id'] ] ) ) {
            echo $cache[ $args['widget_id'] ];
            return;
        }

        ob_start();
        extract($args);

        $title = apply_filters('widget_title', $instance['title'], $instance, $this->id_base);
        if ( empty( $instance['number'] ) || ! $number = absint( $instance['number'] ) )
            $number = 10;

        $interval = isset($instance['interval']) ? $instance['interval'] : 0;
        $instance['category'] = isset($instance['category']) ? $instance['category'] : 0;
        $instance['post_tag'] = isset($instance['post_tag']) ? $instance['post_tag'] : 0;
        if( $instance['category'] != 0 && $instance['post_tag'] != 0 ) {
