It is quite obvious that it doesn't work this way.
If you only select two or three items in Q1 you only rate these in Q2. The rest of subquestions has the same value -> not unique.
Please, read the manual about ".NAOK"

With the correct validation equation "unique(self.NAOK)" and a validation tip it is fine.
Last remark: Do not use the Condition builder, use Relevance equations instead.
Read here about the Pros and Cons of both.

By the way: Your relevance equation of Q2 is not necessary. This is done by the array filter.
A last word. Is it really necessary to force your respondents to click twice for each answer (drop-down-Layout)?
Why not the usual array layout?
