TextAnnotation.InReplyTo is null after setting a correct annotation

Dear Aspose Support Team,

I’m having trouble adding an annotation in response to another one. I have an existing HighlightAnnotation in a document and I want to add a reply to that Annotation but even if both are in same document and page, when I do ta.InReplyTo = item, InReplyTo is still null.
