Keep the first item of the branch in a tree

I made all the steps correctly, in order to have ONE name to each shape and not more, but I notice that in one shape of them (rectangle+arc) I have another one (autre) which is wrong and not supposed to be the result, so I was looking for a solution to keep only the first item of a branch and delete the second ( not delete “autre” because except this situation it’s in the right place) …

List item with index set to 0
