Combine Data: Unexpected Results

I am struggling to understand this unexpected result when I am using the Combine Data component.

I have 3 Lists (List 0, List 1, and List 2).I am using the Shift pattern Component on each of them Then I am taking the resulting lists ( List 0-0, List 1-1, and List 2-2) and running the data through a Combine Data component. As you can see from the resulting data that I am still getting two null items ( Items 2 and 4 from List 2). In simple words: Why are "Emily" and "Jackson" missing from the resulting data list of the combine component? Am I missing something here ?
