Convert Excel Chart to Image - Some Parts of dotted lines became solid lines

Hi,

I did convert Excel chart to image and noticed some parts of dotted lines became solid lines.
Sample code:

                 var options = new ImageOrPrintOptions
                 {
                     ImageType = ImageType.Emf,
                     ChartImageType = ImageFormat.Emf,
                     OnlyArea = false,
                     TextRenderingHint = TextRenderingHint.ClearTypeGridFit,
                     OnePagePerSheet = true,
                     Transparent = true
                 };
                 
                 var workbook = new Workbook(@".\test.xlsx");
                 workbook.Worksheets[0].Charts[0].ToImage(@".\out2110.emf", options);

I’ve attached my test files and a screenshot for your reference. Could you please help to take a look?
