WP SMUSH PRO ISSUE, OPTIMIZE IMAGES SCORE

Hi,
I just finished to smush al my media images files, and when i go to hummingbird, the results are stunning for

Remove render blocking resources: 94
Leverage browser caching : 99
Prioritize visible : 99
Minify JavaScript :100
Minify :100
Enable compression :100
Improve server response time :100
Avoid landing page redirects:100
Minify HTML: 100

But the current score is 26, because my Optimize images score is 6, I optimized my images, re-checked and re-smushed x2, but the result score is the same.
What i have to do after i smush all images to improve my Optimize images score?

Thanks!
