Check under Settings > Permalink Settings and if it's not set, use Post Name. If you're using custom structure, the only thing you want in the text box is /%postname%/ and that should clear it up.
Yes i using /%postname%/ but anyway is duplicate content such as: site.com/post-name/ and site.com/post-name/post-name/
