Unable to display data when using GroupBy method

Hi, I have the same problem as VictorMDiego. Could you send me the “Template Modified.docx” file because I’m a beginner and an example could help a lot

@Fabrizio1976 Unfortunately, we cannot provide “Template Modified.docx” since we do not share customers documents with third persons.
If you have a problem, please attach your template, sample data and code that will allow us to reproduce it. We will check and provide you more information.
