Partition list problem

Hello! I am sorry for asking a simple question, however I am having trouble ordering a certain list. I have 60 branches with 1 item each (one interpolated curve for each branch) and I am using a partition list to re order the data so that I can have six branches with 10 items each. (See photo attached). In the file it is better explained.
