the issue is that you are flattening and renaming the Paths from 1 to 5, while generally speaking, the index numbering of items in a list starts with zero
so when you tell to Sublist to give you items “from 1 to 2”, you are telling it to give you the second and third item of your list
I’d suggest to renumber these branches on the left from 0 to 4, maybe simplifying the definition with something like Entwine + Clean Tree, you would get the very same result with much less components
