As for my IMDB plugin settings...
Where you choose fields to be imported, all of them are shaded green. I've also checked the box "Do not add people from awards...".
Under "Configure", I have the following checked: Use Aka search, Download full credits, Download Movie Connections, Download "Also known as", Download Awards, Download "Episodes", and Download box office data.
