Computed for Display fields are not working. In other words, they do not show anything (blank) or are not updating.
The tell-tale exception --> Put the document in edit mode and press F9 and refresh the form; the field values will update.
The fields that are showing this behavior were at one time not Computed for Display fields or an agent or formula script created them. Either way, if fields exist in the document that have the same name as the computed for display fields on the form, those affected fields will behave like computed fields.
Create a new document that does not have these fields.
Find the code that created the fields if not a design change in the past.
Write an agent or view action to delete the fields from the document(s) affected.
