Only items filed in your Library appear in Context mode. In other words, items in the Inbox are considered "unprocessed" and aren't ready to be acted upon.

To process items in your Inbox, assign contexts/projects and, depending on how you've setup your preferences (see Inbox Processing under the Data icon in OmniFocus prefs), you should be able to click the Clean Up toolbar button (purple hand broom) or hit Command-K to file the items in the Library.

Then switch to Context mode and have a look. Assuming the recently processed actions match your view bar settings, you should see them listed there.

Hope this helps!
