Why is google webmaster tools ignoring my url parameter settings

[mark_baird]

I have set up several url parameters in webmaster tools that do things like select a specific products colour or size. I have set the parameter in google to "narrows" the page and selected to crawl no urls but in the duplicate content section each of these are still shown as being 2 pages with the same content. Is this just normal, i.e. showing me that they are the same anyway or is google deliberately ignoring my settings (which I assume it does when they are sure they know better or think I have made a mistake)?

Allow a couple of month to see the changes. It they were recently made, Google will take a while until removing duplicate content errors.
