When I Copy a Slide, the Font Changes and the Line Breaks in the Shape

Hi. I’m using the latest version of Aspose.Slide (

There are two files in the attached zip
origin.pptx This is the original file.
This is a file that is a copy of the slide from the above file with the origin_out.pptx program.

My source is below.

var copyPpt = new Presentation("origin.pptx");
var basePpt = new Presentation();

var baseMaster = basePpt.Masters;

foreach (var master in copyPpt.Masters)
    master.Name = string.Format("{0}", master.Name);

foreach (var targetSlide in copyPpt.Slides)
    var selectMaster = baseMaster.FirstOrDefault(m => m.Name == targetSlide.LayoutSlide.MasterSlide.Name);
    var copySlide = basePpt.Slides.AddClone(targetSlide,
        selectMaster ?? baseMaster[0], true);

basePpt.Save("origin_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

When I copy a slide from origin.pptx, the font of the characters in the shape inside the slide changes.
Why is this?

Please tell me the cause of the font change and the workaround.
Best regard.
