Setting chart data label from chart workbook not working (C# .NET)

Hello,
I just tried to use the charts "ShowLabelValueFromCell " property to set a custom text for the series labels, unfortunately the lables are not displayed.
If I manually add labels in PowerPoint and set the Value from Cell checkbox to true the previously set custom texts are displayed.
To reproduce just use you Example Gist from Github
Examples-CSharp-Charts-UsingWorkBookChartcellAsDatalabel-UsingWorkBookChartcellAsDatalabel.cs

I am using then latest Aspose Slides Version for Dotnet 19.9

Could you please advise how to make the labels visible.

Thank you
Regards
K.Witt
