DOCX to PDF conversion issue with paragraph margins, drawing charts, Text in tables using .NET

I have issues with converting docx files as byte stream to pdf. There are cases sometimes when paragraphs are moved down slightly causing extra page in an output file. I’m using Aspose.Words v20.7.0 and .NET Core 3.1. I was experimenting with document.CompatibilityOptions.OptimizeFor( Aspose.Words.Settings.MsWordVersion.Word2010 ); and other compability options but without success. Original docx files are created in Word 2010. Obviously I can’t provide you the incoming byte streams so I’ve saved them into file with Aspose.Words as an example.
package.zip (482.3 KB) (filenames are self-explanatory). This is just one example, we have cases where slightly misplaced chart makes few columns covered by text or where word doesn’t fit in the table image (1).png (43.9 KB)
Capture.PNG (61.0 KB)

My source code:
LoadOptions loadOptions = new LoadOptions( )
LoadFormat = LoadFormat.Docx,
MswVersion = Aspose.Words.Settings.MsWordVersion.Word2010,
var document = new Aspose.Words.Document( new MemoryStream( input.DocxBytes ), loadOptions );
document.WarningCallback = new HandleDocumentCallback( );
document.CompatibilityOptions.OptimizeFor( Aspose.Words.Settings.MsWordVersion.Word2010 );

            document.UpdatePageLayout( );
            document.UpdateTableLayout( );
            document.UpdateFields( );
            using( MemoryStream ms = new MemoryStream( ) )
                PdfSaveOptions saveOptions = new PdfSaveOptions
                    SaveFormat = SaveFormat.Pdf,
                    Compliance = PdfCompliance.Pdf17
                document.Save( ms, saveOptions );

I have tried literally everything, most of the issues I had were fixed with adding document.CompatibilityOptions.OptimizeFor( Aspose.Words.Settings.MsWordVersion.Word2010 ); , have no idea what could fix these pointed here. Looking for any help/tips :slight_smile:
