I'm seeing duplicate links listed in open site explorer. Can anyone explain why this might be happening?

For each link listed in Open Site Explorer, I am seeing two identical entries. You can see why this might be a problem for both workflow and data accuracy. Any ideas why this might be happening? Is there a setting or filter that I'm missing?

OSE will show both the www and non-www version of pages. These URLs may go to the same page but the bot considers these two different pages.

<dt>Change the last option in the filter options to "Group By Domain".</dt>

<dt>It should look like this: Show "all" links  from "all" pages to "this page" and "group by domain" </dt>
