Help With Delivery System

I am following the tutorial for Sambapos 3 for delivery system

I am stuck on part 1 adding Store selected Deliverer Name, in that I don’t have it in my list and I don’t see an option of creating it.

I am not familiar with v3 as it is 2 versions behind the currently developed version. But I would think that is Update Program Setting action.

Why not upgrade to version 4?

Sorry I should of said I am on version 4. I am just following that tutorial for delivery system as I don’t see one for version 4.
