Missing Course Content - Appian Developer

I am currently working through the Appian developer learning list, and have come to the Visualize Your Data: Reports and Dashboards lesson (https://academy.appian.com/#/online-courses/816ad062-560d-4de5-a764-531290a3e562), however there appears to be no content whatsoever. Appreciate this could be a issue specific to me, however the reviews are all very negative so figured it may not be. If anyone is able to confirm the issue/let me know where to raise it to, that would be perfect
