How do I fix changing my desktop shortcut icons...?

When I select a shortcut icon and go to change it by right clicking on it, then clicking on properties,and then in web document, I click on change icon and on some of the icons I only get five icons to pick from and not the usual larger amount of icons.

This is the address shown for the five icons shown for the five icons.

C:\Windows\System32\url.dll ................................. Only five icons

And on some shortcuts, I get the normal amount of icons
　
%SystemRoot%\system32\SHELL32.dll................ This one has all the icons which is normal.

Please help. Thank you.

They are icons going to web sites.

when I go to %SystemRoot%\system32\SHELL32.dll this give me a lot of folders and some icons. How do I return the right click to return to normal with the usual large amount of icons..? And yes, I would appreciate your offer to show me how to add new icons.
