Blank 1st page while converting from HTML to PDF using OpenOffice

Question

While converting HTML (the very basic HTML) to PDF, the output PDF always has 1st page blank. How to solve this? Do I miss any specific properties?

xComponent = InitDocument(aLoader, PathConverter(inputFile), "_blank");           
SaveDocument(xComponent, inputFile, PathConverter(outputFile));

 private static void SaveDocument(XComponent xComponent, string sourceFile, string destinationFile)
        {
            var propertyValues = new PropertyValue[2];
            // Setting the flag for overwriting
            propertyValues[1] = new PropertyValue { Name = "Overwrite", Value = new Any(true) };
            //// Setting the filter name
            propertyValues[0] = new PropertyValue
            {
                Name = "FilterName",
                Value = new Any("writer_pdf_Export")
            };
            ((XStorable)xComponent).storeToURL(destinationFile, propertyValues);
        }

I tried to make workaround by deleting 1st page using PDFsharp, but after deleting, it shows me "The documents page tree has invalid node".
