As you can see, I have enabled English and Français, But I only get Wikipedia. I also don't have the 'Apple Dictionary' in the Reference Sources.

This is a bug in the macOS 10.12 Sierra GM (Golden Master).

Apple has released a few more builds since its keynote on September 7. The first build was 16A320.

To update to the current build there are two options:

  1. Wait until macOS Sierra's release date (tomorrow, September 20)
  2. Download the latest macOS Sierra installer from the developer center.

What is your current macOS Sierra build number?
