HB AND PAGESPEED FINDS THE IMAGES ARE NOT OPTIMIZED BUT I RAN THE SMUSH ALREADY

I have smushed them images, tried super smush and smush plugin says all of my images are smushed. But when I look at my Hummingbird score it says images are not optimized. Even google pagespeed says the same.

Also, I can see 2 images are skipped for some errors. Any help is appreciated.
