I canceled at over 33,000 images processed. I have 600+ images

I have a MultiSite toni-esl.com. I stopped the WP Smush Pro plug-in optimization at 33,000 images. I do not have that many.
I have included a screenshot. at the point that I canceled the process.

After I canceled the processing, there was a print message on the left that said I have 250 more images to process. But looking at the circle progress indicator graph of the processing on the right, it indicates that there are many more images remaining to be processed.

What is going on? I have no idea. I think that I should not have done this from network admin, I still doubt that I have that many images. I thought this worked from the media files folder?

Thank you
