I have no idea what could be wrong with the 2 plugins that you’re using. Though I see that the sharing plugin you’re using is also available in widget form. You can add that on the Post – After Content widget area. Then to avoid duplication, disable the one’s placed by the plugin on
Settings -> AddToAny -> Placement
Note: Each WordPress plugin has their own dedicated support forum. You could post plugin-related questions there. No doubt that the original authors know more about their own plugin than I would.
