Issue with course

When I click to start the Learn Relational Databases by Building a Mario Database lesson CodeAlly starts but there is no lesson in the top half the screen as with other lessons. I have double checked 3rd party cookies, did a soft reset of CodeAlly, and tried in an incognito browser (all in Chrome).
Do you have a suggestion on how to get the lesson to load?

Thank you!

So the editor loads but is empty?

Thank you! That helped.
