Can't Link Article to Menu Item

I want to create an link in the top menu item for a specific article. I go to create the menu item and then chose "Single Article" and then below I type in the name of the article. When I go to save the menu item, I get a "Field Required: Must Select Article".

Where do I select the article? I don't see any options for the module assignment to the right.

I'm running 2.5.

Thanks so much!
Below is the screenshot of what I'm seeing...where is the basics tab?

Wow. You are missing all of your configuration options. I would download the newest Joomla Full package, and completely re-install, as something has clearly gone screwy somewhere.
