It sounds like you're referring to what the caddie sets as the club. You can change that to anything you want by either scrolling through the selections with your mouse wheel or by just manually selecting the club you want by hovering your mouse over the club description in the lower left corner of the screen.
You have to have the club equipped so following Joey's advice would solve that.
