Theme stopped showing 300×300 images on home page

or some reason WooCommerce (or may be the theme) has stopped showing 300×300 images on home page. If you check URL you will notice last 5 images are not showing properly.
300×300 are being generated there is no issue as you can directly access those 3 images here:

But on home page it is showing full size image. I haven’t changed anything in theme or any plugin. No idea why this is happening.
I changed theme to another one and problem went away. I changed it back to this theme and problem appeared.
