Nutritionist Pro Online application will require Cache or Browser history to be cleared so new features can become visible on your computer. This is very normal and required for online applications and very easy to do.
Please see the docs attached and pick the browser you are using to clear your history.
Remember a Reboot of the machine is required as well since some browsers wont clear the history until that part is done.
In addition some browsers require a Run As Administrator so that step is also on the appropriate docs.
