Dear community,
In Intelligent Order Management, the sales order has these standard states, going from new sales order, to on hold to in process etc. etc. now I'm trying to customize this

I want different states in different orders however, even when I finally find the state entities (and state reasons underneath), they're uneditable despite me being the owner and sole user of the entire product.

As you can see, all fields are locked; I checked access and have full access. Now if I drill down onto the State Definition Properties, I can edit that property detail:

BUT, changing this, has absolutely no impact on the State reason above:

Does anybody here know how I can customize these states, state reasons and flow? I would really appreciate some guidance, I've been stuck with this for days.
Thank you
