[WP Smush Pro] Always 21 images that needs smushing

I am having problem with optimizing my site svenskarecept.se. No matter what I do I always get result that I need to optimize my images. There is always 21 images that needs smushing (I smush, everything is fine, I run a check, 21 images need smushing, I smush…). The benchmark test always says that "Compressing and resizing https://svenskarecept.se/wp-content/uploads/2018/09/kikartsoppa-695×463.jpg could save 30KiB (82% reduction)." (just one of the images) but I do have an image named kikartsoppa-695×463.jpg in that directory.

What am I doing wrong?!
