Community SupportHi all,
In my environment, the SharePoint site region is US and local machine which has Power BI desktop run is French, getting data use SharePoint folder data source, the [Date modified] column doesn't contain errors. The Power BI desktop version is the latest one 2.56.5023.1021.
In your scenario, please try to run the same desktop version as ours then test again. If issue persists, would you please share detail steps for us to reproduce the issue?
Best Regards,
