WP Smush Lossless Compression Problem

I am having problems with images not being losslessly compressed by WP smush.

I am trying to improve the Google PageSpeed insights score for my client to help with rankings and it is coming back saying that the images on the home page have not been losslessly compressed by WP Smush says that they are.

I have tried deactivating and reactivating and also deactivating and reactivating the super smuch setting but nothing seems to be working.

Can anyone please help.
