Need help on query editor issue as its not showing errors

I have downloaded latest version of Power BI. I loaded data from csv files to query editor. One of the file has empty rows. So as per query editor documentation and the udemy tutorial, query editor shows green/red bar in between data rows and header. But in my system i am not seeing that green bar.

As per document - Document (marked with black arrows)

In My system - My system (marked with black arrows)

Also, as per udemy tutorial, when we hover the mouse over the columns it shows a information box. In that box we can see the stats like valid % error %, empty % and remove empty row. But I am not seeing that as well in my system.

Need help on both the issues. Or pointer to any document, link, settings. Any help will be really appreciated!!

Thanks in advance!
