It seems you have deactivated the ShareThis Plugin.
But in your website code, we can see that ShareThis SPAN tag code is still present. Which seems to be implemented manually apart from Plugin installation.

If the Plugin is deactivated, then this code should not be present in your site code.
So this can be a reason behind duplicate buttons. Please remove the above code and activate the Plugin and check again.
If you still face the same issue, then we suggest you to deactivate all other installed Plugins and check again.
