[ISSUE?] Knowledge Check — Lesson 7. Data Aggregation

I already finished the L1-AP] Data Literacy with KNIME Analytics Platform: Basics.

Since the beginning I thought the exercise provided below has an issue but because I was still studying I decided to give it for granted. Now I am preparing for the certification and doing it all over again and I still think (please change my mind) that the exercise has an issue.

The exercise does not specify the date format for the birth date but generally speaking the lower the date is the older the person is and viceversa, I assume the date format starts with YYYY and YYYY for both fields. What I am missing? I just got all the course super easily but this silly exercise is melting my brain so badly.
