Do you mean the report visual show wrong data after refreshing data source in Power BI Service? Or do you mean the report visual keep the original result even you have updated the data source? While this problem doesn't occur in Power BI desktop, right?
Was the data still wrong after refreshing the report page manually after updating the data source? Could you please try to re-publish the report?
Besides, what is the data source? Do you use import mode or live connection to fetch data? Do you update data source manually or on schedule?

I use Power Bi with SqlServer, so the information on the desktop is correct, when I upload the file the report returns wrong values, so if I download the same report and open it on power bi desktop and click refresh, it displays me the information correctly.
