Why is the first cell in my listbox not colored properly?

[Asasafuchi]

So I am trying to color each row in my listbox as such where the colors are defined in an array fille with color box constant but for some reason the first element is not getting colored properly. Does anybody know why?

Is the first row selected? This would make the first row appear in another color.

Right-Click listbox -> Selection Mode -> Highlight entire Row.

Hi, no the first row isn't selected. I managed to solve the issue by changing the data type of the listbox from scalar to array. But I would still like to know why it didn't work in the first place. What did this change to exactly?
