Having social buttons on certain pages is not always desirable. For instance, I would like to have the option to exclude the buttons from my Contact and About pages (or any other pages). For now I have to hide the buttons with CSS, but that’s not the best solution.
Based on the plugin info on the WP plugin repository, it seems that adding the buttons on pages is optional.
Try to look for any custom plugin options to enable or disable the buttons on your page editing window on a per-page basis.
