Those statuses for orders are just a background feature and aren’t customizable. Those are just to show what step in the process the order is in but it is an old feature that isn’t used much anymore. I’m not exactly sure which statuses for order lines you are looking at. Where is that shown? Is there something specific you are trying to accomplish with those statuses?
You are also standard support so you can email support@cetecerp.com for any questions as well.
