Previous trigger and layers
When a trigger shows a layer, that layer remains open until another trigger hides it. That's done directly with a "Hide layer" trigger. Or it's done when a trigger shows another layer for which the Slide Layer Properties indicate to close other layers.
That's the long way of saying that if you don't want a layer to show when someone returns to a slide, you need a trigger to hide it.
For example, you could add triggers to the PREV button that hide each layer. Note that those triggers must come before the trigger that jumps to the previous slide.
Another option would be to add triggers to hide each layer when the slide's timeline starts.
Your post says you want the user to "go back to the previous layer." That's also doable. For example, you could use a variable to track which layer is open when the user leaves the slide, and then use triggers with conditions to show the appropriate "previous layer" when the user returns to the slide. IMHO, that isn't worth the effort. In fact, it could be confusing to the user .
