Array.append(int) in for loop, appends NULL values instead. User error or bug?

There is code in the assign labels area of my Source (in the arrivals tab) that assigns a patient type to tokens. (The label named type) I think the logic for selecting the type works fine, but I can't append an integer to an array for some reason and that's messing everything up.

Posting my model. Here's what it looks like. In the same loop I append to another array and that one works as expected. I am printing the values before and after each append and something here is just not working as expected.

Any help?

Answered my own question...

I should be using Array.push for an integer or double.

Array.append appends another array.
