Get rid of the words "Project" and "Context" and you should be good...it is trying to file your actions in a project called "Project Misc" and a context called "Context Home" and when it can't match them it leaves the values unset, which means it ends up in the Inbox. I agree the documentation is a bit unclear on this point, and an explicit description of what an example like

-- Another Action > Project 2 @ Context 3

actually does (creates an action named "Another Action" in the project named "Project 2" with context named "Context 3") would reduce the potential for confusion.

So, for your case:

Buy some widgets > Misc @ Home #Friday

should give you an action "Buy some widgets" in the Misc project, Home context, due date of Friday.
