Grip pen not showing up on wacom tablet driver

New user here.

I just bought a new bamboo replacement grip pen stylus and it would not respond fully when used with my intuos4 tablet and Macbook pro.
The replacement grip pen stylus i bought is from dreamworks:
Wacom Bamboo Stylus Nibs Set Case for CTL, CTH, CTE, MTE, INTUOS

One thing i noticed that seems amiss is that the grip pen icon does not show up on the wacom tablet driver control panel.
All i see there are;
Device - Intuos4M
Tool - Functions & Mouse
Application - All

I have removed and re-installed the drivers from the wacom website a number of times using;
Latest Driver for Intuos Pro [this shows the mouse icon under tools]
Latest Driver for Intuos [this does not show the mouse icon or the grip pen under tools].

I have attached images of the new bamboo pen stylus and a screen grab of the wacom driver control panel i get on my macbook pro after installing the driver for Latest Driver for Intuos Pro.

Can someone please advice me on what to do to get things working.

Thanks.
