In the stylesheet for SCLogin, there is the following style
.sclogin-social-login .pull-left {
margin: 5px;
}
You can update it to
.sclogin-social-login .pull-left,
.social-login.reconnect.pull-left {
margin: 5px;
}
The file is found in /media/sourcecoast/themes/sclogin/default.css (or sourcecoast.css). I'll put an issue in our tracker to make the spacing consistent and it will be in the next release, so you should be able to edit that file directly and not have to worry about making an override for the theme.
