Hello,
when cloning a presentation created from a French version of powerpoint, the Chart data are lost in the cloned presentation when making a right-click on the chart to edit data values.
Seems it comes because the clone method when creating the new pptx file is renaming the excel sheet referenced (from 'Feuil1' because it's a french version of powerpoint to 'Sheet1'). So the data references are no more found by powerpoint.
My Test project attached
You will see that the 3D format of the chart is removed too
Thanks
