The reason you’re only seeing one value is because there is only one label element. When you feed “Set label” a list, it will simply run through the list and set the single label element to each value in turn. so, faster than you can see, it sets it to A, then B, then C, which is why you only see C.
Human UI is notoriously bad at “dynamic” elements. You just can’t add/remove elements on the fly.
If you can set a cap on the number of possible elements, then you can fake it a bit by creating, say, 20 labels, and dynamically hiding/showing them with Hide/Show Element, similar to this answer: HumanUI: ...but I DO need to drive the creation of elements with the results of a value listener...? - #2 by andheum
