wp smush pro not compressing all the images

Hi guys,

I have an issue with wp smush pro that is not compressing 107 images. Each time when I click to "bulk smush now", it starts to compress 5-10 images and after that it is showing a success message. But when I enter to smush pro again, it shows me 107 images left to smush.

How can I reset it and smush everything again?

You can access to the admin of that site.

Thank you.
