Chart legend labels lost after saving presentation

Hi, we have a presentation with a chart. The chart has a legend with the series name (AAA LLL, BBB LLL, CCC LLL, …).

The issue is that if we open this presentation and save it with the following code, the chart loses the series names and the shows Series1, Series2, Series3… as legend labels.

var pres = new Presentation("Test1.pptx");
pres.Save("Test1.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

Could you please provide a solution to this issue?

Attached our test presentation and the chart screenshots before and after saving presentation.
