you'll get some lengthy explanations and advice following this I'm sure. best I can do is guess that either the extractor is incorrect/missing or the bolt is bad somehow.
Best advice you'll get on repairs is that you need to send the WHOLE GUN IN for warrantee work. that way they can check it as a system before they send it back. this site is littered with people who refused to do that and had no end to problems as a result.
