Something goes wrong with EWWW Image Optimizer plugin

It seems to me that after updating of EWWW Image Optimizer plugin for WordPress it doesn’t work properly. Google Page Speed Score says me that images are not optimized on my site apple-iphone.ru. Usually Google’s Page Speed Service says that all of my images are well optimized. Could you please check it out?
