Thanks for your inquiry.
Unfortunately, your issue is not resolved yet. The responsible developer has completed the analysis of this issue and the root cause has been determined. The fix to this problem actually requires us to implement a new feature in Aspose.Words’ API and I regret to share with you that this problem has been postponed till a later date. There’s no ETA available at the moment. We will inform you as soon as this issue is resolved. We apologize for your inconvenience.
Secondly, if you please execute the following code, you will observe that in this case Aspose.Words does not insert an extra Section break at the start of final document (out.docx).
dstDoc = new Document();
srcDoc = new Document(@"C:\Temp\Title+Area.docx");
// The destination document is not actually empty which often
causes a blank page to appear before the appended document
// This is due to the base document having an empty section and
the new document being started on the next page.
// Remove all content from the destination document before
