Image Optimisation issues

I could notice 2 issues:
1) Images are still listed as not optimised in the Performance Test in Hummingbird, however the images show as smushed.

2) After updating WP Smush Pro to latest version, and when clicking on the individual images under Media > Library, the popup is loading a blank screen.

The issue resolved once Smush Pro plugin is disabled.
