Floating social bar duplicated

Great plugin that loads super-fast!! I have an issue….

When the post hasn’t related post the floating social bar doesn’t appear duplicated. For example:
http://www.ecomotriz.com/2014/02/mojacar-bicicleta-electrica-bici-e-bike-21-febrero/

But at posts, where there at the bottom there are related posts, in the floating social bar appears 2 Facebook buttons, 2 Twitter buttons, etc. Here an example:
http://www.ecomotriz.com/2014/03/supercargadores-tesla-puntos-recarga-europa/

It seems the plugin detects the posts and “believes” that it can share also this posts.

Any solution?? Thank you in advance!! 😀
