Videos about "Style Guide Architecture" training course are NOT working?

Hi all,
I'm trying to do the Style Guide Architecture" course in the Training section, however when I click on the videos, I get an error message saying "Lesson not found!". It seems only the quiz is available but no videos... Can somebody from the staff enlighten me when will these videos be available?

 Here is the link for the mentioned course:
