Slide Layer Order

I've come here looking for an answer to the same problem, but I'm still confused.

Does the layer order (as they appear in the "Slide Layers" panel) take precedence for the object stacking order or does the order in which the layers are triggered override the stacking order? I would have thought the layer order (in the panel) takes precedence (ie. objects on upper layers sit ON TOP of lower layers, no matter when they are revealed.

Even Google's AI summary, when I was searching for an answer to this question, states:

"In Articulate Storyline, the slide layer order refers to the stacking sequence of different layers on a single slide, where the layer listed higher in the "Slide Layers" panel will appear on top of the layers listed below it, meaning objects on a higher layer will visually appear in front of objects on a lower layer; essentially, the order you see them listed is the order they will be displayed on the slide."

But the linked articles that Google provides are not that clear. This article seems to suggest that the trigger order sets the stacking order and I should create multiple triggers to re-establish the desired layering, yes?

Here's what my project looks like:

For the 3 layers:

1. The top layer contains a consistent slide title, "Policy summary..." (that I want to show at all times on that slide) and is triggered when the timeline starts on the base layer (#3. below). I've selected this layer in the screenshot above so it shows the title.
2. The 2nd layer has a text definition that appears under the title, an image that contains the same colour as the background (it's used for a hidden animated reveal) and it is larger than the slide title's position (ie. it covers it) but I want it to sit UNDER the title. The idea is to have an image, that refers to each policy point, animate out from under the background image panel, on the right side and then when the next policy point is shown, it animates back under the panel. I trigger this layer 1 second after timeline starts on the layer, but the image (with background colour) is appearing ON TOP of Layer 1 - shouldn't it be UNDER the title that's on Layer 1?
3. Contains the base layer with slide banner and background.

I plan on adding many more layers like layer 2 (for additional policies) but I need to get the ordering right first, which will depend on whether the layer ordering OR the layer triggering takes precedence in setting the object layering.

If "trigger order" is setting the object stack order, I'm guessing I'd have to trigger the layers in reverse order (from how they appear in the Slide Layers window) to make them sit in the right order on the screen, yes?

Your confirmation/guidance would be MOST appreciated 🙂
