That could be because Staff is working on the Admin bar. Do you have any other issues you need help with?
P.S. As your are new these links will be helpful. On the bottom of your Admin page you will find a link to the Learn WordPress.com blogging Tutorial prepared by Staff. http://learn.wordpress.com/ The support documentation is all found at the Support link http://en.support.wordpress.com which is also on the bottom of your Admin page.
That makes sense; I just checked, and they are all the same again. (I did check the ‘documentation’ but couldn’t track down what I needed…sometimes, just knowing what things are called is Very Helpful. For now, I’m muddling through okay…I think.)
