HPDFDoc

Field	Purpose
`FieldCount`	Number of form fields written to the FDF `/Fields` array on export, or of 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 discovered
`Status`	The FDF `/Status` value carried out of an export or reported back by an import

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