C2W1_Assignment Extercise 9

The answer seems ok, which means it says no anomalies were found. I don’t understand why I am getting half number. Means instead of 10, I am getting 5. I have passed the assignment, but curious to know, whether I am not understanding anything

I run into same error. I put the “Expected:” and “but got:” into a text differ. All diffs are related to feature.string_domain for all features in domain_change_features in Exercise 8.
I suspect the grader is wrong.
