Do you have a plugin that is called "Share This copy and paste"? It seems like this issue is coming from a plugin or something similar because they are adding the codes as you can see here, http://screen.stackideas.com/2015-03-17_0057.png
hi " Share This copy and paste " not plugin -- easyblog have share this botton bokmark
easyblog -- settings -- Publishing Tools -- Bookmark button ( When I tried (actived = scroll || Disable == fixed) )
It seems like Share this is adding another layer of div which causes issues on RTL I would reckon that you turn that off if you don't use it. Anyway EasyBlog already has social bookmarks so you don't really need this
