Unable to extract all pdf fields

I am trying to extract all form fields using a trial version of Aspose.PDF 23.7. However, it is not able to extract all form fields.

Please find attached sample pdf.

Is it because I have a trial version? If so, this is fine. We are trying to check the functionality to decide if we want to buy it or not.

Thanks.
