Defined X in PPTX Is Not Shown in the Exported PDF File

I have a chart with 4 lines

Presentation presentation = new Presentation(inputPath, loadOptions);
presentation.Save(outputPath, SaveFormat.Pdf);

Input and output files are here:
hiddenX.zip (35.9 KB)

You can see that the the defined X in pptx file does not appear in pdf file.
