App images on desktop

The icon images on the app screen are specific to the website they link to, but when I pin them to the Start menu, many of them become the generic "e" for explorer icons. They do retain the name of the website, which is okay, but if I change the size to "small", I am left with a bunch of similar-looking icons. How do I (or, can I) fix this?

Thanks.

You could try rebuilding the icon cache:
