Badge duplicated

Hi there,
and thank you for writing in!

Please try adding the following code snippet to your theme functions.php:

if ( !class_exists( 'YITH_WCBM_Customization_Print_First_Only' ) ) {
    class YITH_WCBM_Customization_Print_First_Only {
        private static $printed = array();

        public static function check( $badge_html, $id_badge, $product_id ) {
            $my_id = $id_badge . '-' . $product_id;

            if ( in_array( $my_id, self::$printed ) ) {
                return '';
            }

            self::$printed[] = $my_id;

            return $badge_html;
        }
    }

    add_filter( 'yith_wcbm_get_badge', array( 'YITH_WCBM_Customization_Print_First_Only', 'check' ), 10, 3 );
}

Please try this solution and let us know if everything works fine!
