Presentation crashes on saving when adding custom legends


I’m using aspose.slide version 7.1 to create a .pptx presentation. I am adding a ClustoredColumn chart to my presentation. When I add custom legends to the columns, open the presentation and try to save it, it crashes. Please find bellow the code I am using:
SlideEx sld = pres.Slides[0];
Aspose.Slides.Pptx.ChartEx chart = sld.Shapes.AddChart(ChartTypeEx.ClusteredColumn, 100, 100, 400, 400);
chart.ChartTitle.Text.Text = “Sample Title”;
chart.ChartTitle.Text.CenterText = true;
chart.ChartTitle.Height = 20;
chart.HasTitle = true;
ChartDataCellFactory fact = chart.ChartData.ChartDataCellFactory;
chart.ChartData.Categories.Add(fact.GetCell(0, 1, 0, “C1”));
int Id = chart.ChartData.Series.Add(fact.GetCell(0, 0, 1, “Series 1”), chart.Type);

ChartSeriesEx series = chart.ChartData.Series[Id];
series.Labels.ShowLeaderLines = true;
int defaultWorksheetIndex = 0;
series.Values.Add(fact.GetCell(defaultWorksheetIndex, 1, 1, 20));
series.Values.Add(fact.GetCell(defaultWorksheetIndex, 2, 1, 50));
series.Values.Add(fact.GetCell(defaultWorksheetIndex, 3, 1, 30));
for (int i = 0; i < 3; i++)
DataLabelEx lbl = new DataLabelEx(series);
lbl.TextFrame.Text = (i*10).ToString(); //<-- this line is causing the problem
lbl.Id = i;

When I run this code, I am able to generate the presentation and I can open it successfully. But if I try to change anything in the presentation and try to save, it crashes.

Thank you in advance,

Thank you so much for your reply. Being able to set custom legends for column charts and being able to change and save the presentation afterwards is very urgent to our business since the client asked for it. So could you please give me a time estimate on when this issue will be fixes since I need to communicate that with the client.

Thank you for your understanding,
Sami Simon
