With the Social Sharing app, you can only have a combination of 3 Social Buttons with analytics (FB, LI and twitter) and or you can have the 4 Like/Recommend Buttons without analytics ((FB, LI. Twitter and Google+). If you want the analytics, but also want G+, you can add the 3 buttons with analytics and separately add the Like/Recommend Button for G+, but it will not have analytics.
