Cocos2d-x 3 beta : polygon not drawn right

Im using DrawNode as recommended to draw polygon but the problem its not drawn right as i like.
i attaching the images of the desired polygon shape and one that is output of my code that output wrong . the code :

if (sprite && sprite->init())
{
        sprite->setTextureRect( Rect(0, 0, 200 ,200) );
        sprite->autorelease();        
        auto draw = DrawNode::create();
       
        {
       
		Point Block1[] = {
            Point(0,0),
			Point(30,0),
			Point(50,10),        
            Point(80,10),
			Point(100,0),    
            Point(200,0),
			Point(200,40),               
            Point(100,40), 
			Point(80,50),
			Point(50,50),
			Point(30,40),
			Point(0,40)
        };

 

        draw->drawPolygon(Block1,12 ,Color4F(1,222,120,1), 1, Color4F(0,0,1,1));
        } 
        sprite->addChild(draw, 10); 

 }

 {
        CC_SAFE_DELETE(sprite);
