That’s not true. Each item is now output as individual bundles. The example values you see per your last screenshot are for the first item, but each item will now individually be sent to subsequent modules – you just have to map the item’s variables from the [51] Iterator module.
Give your scenario a run and see how many output bundles come out of your Iterator module.
If you want to learn more about Make, you can read up in the Help Center. I also recommend doing the tutorials in the Make Academy, and learn advanced skills like how to make custom apps to any API in the Make Partner Training Portal - both have certificates for successful completion.
