Size of images / thumbnails

Thank you spashingpixels.com

I went to Woocommmerce Settings > Catalog tab and I changed the size of the images as follows

Catalog Images 200 Width 200 Height
Single Product Image 600 Width 600 Height
Product Thumbnails 90 Width 90 Height

and I saved the changes

And when I see my products the images do not reflect these sizes.

Here you can see the products

Why is that? How can I change the size??

Thanks!
