Keeps saying you have images that need re-compressing for Smush Pro plugin

I have a very similar problem as this post:

https://wordpress.org/support/topic/keeps-saying-you-have-images-that-need-re-compressing/

It keeps telling me I only have 108/110 attachments smushed no matter how many times I bulk smush.

When I click recheck, it tells me that there are 10 images that need to be smushed. When I hit bulk smush, it says all attachment have been smushed but the right box shows 108/110 smushed. When I go into the media library, it doesn't look like there's any images left that need smushing. Could you please help me fix the issue? Thanks.
