Sophia.org, Please Correct Your Course

[Mab81]

I am hoping someone from Sophia will read this since they seem to lurk now and then.

I am taking the Art History course, and am really enjoying it aside from one huge problem.

You have entire sections which contain duplicate content of another section, when they are supposed to be on an entirely different topic. I sent in a help ticket to the learningcoach email 9 days ago but got no reply.

Unit 2 - Challenge 4: Romans and Eutruscans - Concept 6, "Recognizing Elements of Roman Architecture in Greek Temples" has duplicate content fro the previous section, Concept 5, which is about the invention of concrete. But the challenge question for that section *is* on the correct topic, which means I can't answer the challenge question because the curriculum for that topic is missing. 

The same problem exists for another chapter. 
In Unit 1, Challenge 4: Language of Art, sections 3 and 5 are identical in content. 

I really need to be able to read the correct content before I take any more milestones. It's very difficult to try to take challenge questions and milestone questions on content that doesn't exist.

Thank you for any help!
