Dynamic property

1. I have downloaded the latest version of Jetpack and the files are identical to the ones I have on my local server.
2. I correct the path: C:\wamp64\www\artehistoria\wp-content\plugins\jetpack\_inc\lib\admin-pages\class.jetpack-admin-page.php on line 67
3. The other path is correct: C:\wamp64\www\artehistoria\wp-content\plugins\jetpack\class-jetpack-gallery-settings.php on line 34

class.jetpack-admin-page.php on line 67: $this->jetpack = $jetpack;

public function on_jetpack_loaded( $jetpack ) {
	$this->jetpack = $jetpack;

	self::$block_page_rendering_for_idc = (
			Identity_Crisis::validate_sync_error_idc_option() && ! Jetpack_Options::get_option( 'safe_mode_confirmed' )
		);
	}

class-jetpack-gallery-settings.php on line 34: $this->gallery_types = apply_filters( 'jetpack_gallery_types', array( 'default' => __( 'Thumbnail Grid', 'jetpack' ) ) );

public function admin_init() {
	/**

	 */
	this->gallery_types = apply_filters( 'jetpack_gallery_types', array( 'default' => __( 'Thumbnail Grid', 'jetpack' ) ) );

	// Enqueue the media UI only if needed.
	if ( count( $this->gallery_types ) > 1 ) {
			add_action( 'wp_enqueue_media', array( $this, 'wp_enqueue_media' ) );
	add_action( 'print_media_templates', array( $this, 'print_media_templates' ) );
		}
	// Add Slideshow and Galleries functionality to core's media gallery widget.
	add_filter( 'widget_media_gallery_instance_schema', array( $this, 'core_media_widget_compat' ) );
