Some Chart Labels Disappear when Converting from PPTX to PDF

Hi Team,

With the latest version of Aspose.Slides - 21.12 PPTX to PDF some chart labels disappear (see the attached PPTX and PDF PPTX-to-PDF.zip (238.2 KB)).

Here is the code I used to reproduce the issue:
// Instantiate a Presentation object that represents a PPT file
Presentation presentation = new Presentation(“test.pptx”);

        // Save the presentation as PDF
        presentation.Save("PPTX-to-PDF.pdf", SaveFormat.Pdf);

Is there something I can do to prevent this?

@ipeadmin,
Thank you for contacting support.

Unfortunately, I don’t see a workaround to prevent this. I’ve reproduced the problem with chart labels and added a ticket with ID SLIDESNET-42986 in our issue tracking system. Our development team will investigate this case. You will be notified when the issue is resolved.
