HPDFDoc

Field	Purpose
`FieldCount`	Number of form fields written to the FDF `/Fields` array on export, or form field dictionaries applied to the document on import
`AnnotationCount`	Number of annotations written to the FDF `/Annots` array on export, or annotation dictionaries applied to the document on import
`StatusPresent`	`true` when a non-empty status string was supplied or found
`Status`	The FDF `/Status` value carried out of an export or reported by an import

Both THotPDF.ExportLoadedInterchangeToFDF and THotPDF.ImportLoadedInterchangeFromFDF reset and fill the record, including on early failure when only Status is known
Widget-only fields without a partial name are skipped on export and therefore not counted in FieldCount
Compare FieldCount and AnnotationCount against the include flags you passed to confirm what the stream actually contains
