The "default" column allows you to select the default value you want for the field. You need to turn off "skip", take the customer off hold in receivables, recall the order, and change the "on hold" value on the order header manually. If the customer is still "on hold" in Receivables when the order is recalled, you will not be allowed to change the status. You will not be allowed to invoice the order until the "on hold" is removed from the order header.
