Depending on how some WordPress themes handle what’s referred to as “the excerpt”, some users may experience the share text (Tweet, Share, Pin, +1, etc.) showing up in their post excerpts.
We’re currently tracking this issue on Github and are working a fix.
Once we find a solution we will update it on Github and push out an update to the plugin.
In the meantime, the best way to get rid of this is to go to Social Warfare > Display Locations and have the buttons only render Below posts. As long as you have the floating buttons activated, visitors will see them right away, they just won’t show up before the beginning of the content.
