On a first look, that seems to be a typo, but @Moritz, who is the author of the case, is better positioned to tell.
You might also find this useful is you're practicing cases at the moment:

        Yeah, not all cases are 100% correct. When you find these type of inconsistencies when practicing, there isn't an interviewer you can ask which number to use (or why there are two different numbers).
In that case, just assume on of the numbers and move on.
