The Flip Matrix component requires that the data tree be structured like a 2D matrix, with rows and columns that can be swapped. In your case, you should use the Path Mapper component with the mapping {A;B}(i) → {A;i}(B). If maintaining the tree structure isn’t essential, you might consider trimming your tree instead.

By the way, I don’t have Pufferfish so just skipped it. You probably want to restore that.
