Q. When right-clicking on the Edit Data table, why does the menu containing the Add ‘Nutrient From’ Column option not display?
A. The antivirus software may be the issue.
Norton Anti-Virus tool bars can disable the user’s ability to right click and view the Add Nutrient from Column Menu. For this option to be available, the Norton Anti-Virus tool bar needs to be disabled.
To disable this toolbar, go to the Customize and control Google Chrome button 
in the upper right hand corner of the web browser. Select More tools / Extensions. Uncheck the Enable option for the Norton toolbar.
The right-click functionality should now be available in the Edit Data table.
