I smushed a few images but didn't smush the originals.

Hi, I smushed a few images but didn't smush the originals. I *want* to smush the originals, so I have updated my settings. When I go back to smush the images the Smush Now! button is gone, and replaced by the Smush Stats. So there's no way for me to re-smush the image to also smush the original. Is there a workaround or did I miss a step? Thanks
