Hi!
For some reason, I bet CC has already answered your question! But since I don't really know, I'll try to answer your question as well. It looks like in your Array to Cluster function you have the Cluster size set to 6 elements. This means that no matter what the size of the array you are giving to the Array to Cluster function, it will only output a cluster of 6 elements. So, this means that all of the "[5][5][5][5]..." elements are just repeats of the [5] element.
To change your "cluster size" you can right click on the Array to Cluster function and choose Cluster size. Note that this setting cannot be changed programmatically.
Hope this helps!
