Annotations

Hello

We are using aspose pdf 9.5.0 to get all the annotations of a page and get the highlighted text.
It is working great on most of the pdf file, but not in the attached one.
I am not able to get the text of the annotations inside a table (see attached file)
The code is :
AnnotationCollection annots = page.getAnnotations();
        for (int j = 1; j <= annots.size(); j++) {
            com.aspose.pdf.Annotation annot = annots.get_Item(j);
            if (annot instanceof HighlightAnnotation){
                HighlightAnnotation linkAnno = (HighlightAnnotation)annot;
                com.aspose.pdf.Rectangle rect = linkAnno.getRect();
                if (annot.getName() != null) {
                    TextAbsorber absorber = new TextAbsorber();
                    absorber.getTextSearchOptions().setLimitToPageBounds(true);
                    absorber.getTextSearchOptions().setRectangle(rect);
                    page.accept(absorber);
                    String text = absorber.getText();
                    System.out.println(text);
                }
            }
        }

This code is returning the text of the annotation named TITLE, but it is returning empty value for the annotations named BON and COMPTE.

Can you advise please,
Thank you,
