NPS score display in Dashboard with loop & merge function

Hello all,
I used "loop and merge" to repeat NPS questions & drivers for all brands selected (multiple choice) in 9 surveys .
In fact I have 15 brands * 9 surveys = 135 brands possible choices ( 5 brands are similar for the 9 surveys, the 10 others are different)
In the dashboard (consolidating the 9 surveys), when I want the NPS score by countries for each of the 135 brands, I don't manage to get all the brands, here is what I get :

• Brand choice 1 (so this NPS score is an average of 9 surveys with brand 1 selected)


• Brand choice 2.........


• Brand Choice 15

• Brand 1


• Brand 2


• ....


• Brand 135
