Question: What happens when an Order Status has no order state as none of these order status had a assigned state referring to magentodomain.com/index.php/admin/sales_order_status/

Question: Is a blank state assigned "processing" by default ?

• Our ERP picked this up as "processing" after disputed -whereas should be canceled

Status	status code	default status	state code
PayPal Canceled Reversal	paypal_canceled_reversal
PayPal Reversed	paypal_reversed
Pending PayPal	pending_paypal

Changed it to

Status	status code	default status	state code
PayPal Canceled Reversal	paypal_canceled_reversal	No	canceled [Canceled]
PayPal Reversed	paypal_reversed	No	holded [On Hold]
Pending PayPal	pending_paypal

• Pending Paypal left blank because this never appears in 7yrs of orders
