WP Smush + ACF Crop Image

I've noticed through a Performance Report (Hummingbird) that many of my images are still not optimized, but in the WP Smush dashboard, it is reporting that all of images are smushed.

Under my "Benchmarks" in Hummingbird, it references all of my images that were generated by the plugin 'Advanced Custom Fields: Image Crop Add-on". This is an ACF field that forces cropping and adds the image to the media library. For whatever reason, WP Smush does recognize them in the media library at all.

Please advise.
