In fact, here's the specific situation with regards to this section of the course.

That's clearly a bug, that last column is obviously "CarID" from the derived table.

You might want to forward this to Support.

I think I know what he means and I have experienced the same problem. While not the same example as above, here's another instance where the column headers are offset incorrectly.

SELECT * FROM Car INNER JOIN Model ON Car.ModelID = Model.ModelID;

The joined table has 3 columns, but the last column has no header. The first column has the header for the second column, the second has the header for the third leaving the third blank.
