I cannot figure

Hi,
I cannot figure what is going on. I upgraded to Smush Pro, and all of my images were optimized successfully. When I go into the media library, the images do show up. I can't figure out how to make a compressed image the one that will appear in on Divi page. No matter what browser I open, no matter how many times I clear the cache, an example image stays the same at 1.6 MB. So, I figured I would try going into the divi page itself and edit the image and change the size manually. However, when I click to edit the image, a different image from the library appears, not the one I am working on. Any suggestions?
