doc.MailMerge.DeleteFields() Removing white space left by this method

What is the easiest way of removing the white space left by doc.MailMerge.DeleteFields() after calling it? As the white space left by several stacked up mergefields can be very unsightly!!

Hi,

Thank you for considering Aspose.

Are there empty paragraphs left or somewhat else? Please attach the document before deleting merge fields.
