Hi guys, I created a bill approval workflow but there's a problem couldn't figure out. Everything works as intended including the disabled Approval Status and Next Approver fields when a bill is created. However, when I edit the saved bill, those 2 fields will be come editable again. How do I disable it so that no one can change them when they edit the bill?

Use Set Field Display Type?

is the bill exiting the workflow? if yes, those conditions no longer apply

these are the actions for the start of the bill creation. Set field value is disabled-before record load but the 2 fields are editable when I edit a newly created bill
