This is an oversight. Thank you for pointing it out.

I have just corrected it by making 2.0 identical to 3.0. Normally,
I would not change 2.0, but would instead make a new version 2.1 in
order to make corrections such as this. In this case, I have not
made a new version because we are at the very beginning of the term.
For future corrections as the term progresses, I will always make
a new version instead of changing the existing version.
