Aspose.PDF .NET Replaced or redacted text still searchable

Aspose.PDF Product Family
1

After replacement of the text in document (or after redact) in selected area (rectangle) the edited document in Acrobat Reader DC and text that was replaced or redacted is still searchable (but on the preview is not visible). This problem occurs only for this document and only in Adobe viewer (others work fine).

var rect = new Aspose.Pdf.Rectangle(llx, lly, urx, ury);
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber();
textFragmentAbsorber.TextSearchOptions.LimitToPageBounds = true;
textFragmentAbsorber.TextSearchOptions.Rectangle = rect;
textFragmentAbsorber.TextReplaceOptions.ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.None; //.AdjustSpaceWidth;
doc.Pages[shape.p].Accept(textFragmentAbsorber);
foreach (TextFragment tf in textFragmentAbsorber.TextFragments)
                        {
                            tf.Text = "";
                        }
Alternatively
//editor.RedactArea(shape.p, rect, System.Drawing.Color.LightGray);

Do you have any solution regarding this?

TestAposePDF.zip (2.4 MB)

attached: standalone console application. In debug folder there are 3 sample files: source (instrukcja.pdf) and 2 output files (instrukcja_out.pdf - after text replacement and instrukcja_redactout.pdf after redact). On first page I’ve tried to replace word (or redact region) “obsługi”. It’s invisible during preview in Adobe viewer. But if I press ctrl-a, ctrl-c and paste to notepad I see whole text (including “obslugi”)
