Bug when using Aspose.Pdf.Document.Pages.Insert and page layouts are different

Hi
Am using latest pdf dll for .net 2.0 version10.2.0.
With
Aspose.Pdf.Document IndexDoc
Aspose.Pdf.Document MainDoc
When using MainDoc.Pages.Insert(1,IndexDoc.Pages) and IndexDoc is portrait and MainDoc is landscape, the Inserted page from IndexDoc is blank in the MainDoc.
Attached URL links to zip of VS2010 c# app to demonstrate this.
Please advise if any workaround exists.
Thanks
