Hello,
The icons on your footer with heading We Are Social is a widget, that you can manage at Appearance >> Widgets.
The other icon staying at the very bottom left of your website is the floating social media icon, the icons that fly and floats.
As per our review, your website have some javascript breaking issues, may be from other plugin or theme. and This breaking breaks our plugin animation. This is the reason the icon staying there without any moving/fly animation.
So consult your web designer/developer and identify the issue and resolve it. It not only breaks our plugin but can break any other plugins which use javascript/jquery.
