[WP Smush Pro] Optimizing images issue

Hello Sir,
I have a problem in optimizing images through my site
I used your app and optimized the images with 2X option but check my gtmetrix details you will find that optimizing images hasn't been done yet through the following link


I waited for the plugin for 2 days till yesterday to finish and told it's finished and today when i checked the pugin it says it's only 67% done! but mo optimization on the page speed (optimize image still needs work).

Any help with that?
