Not able to change centering issue with shortcode or widget

Hi there,

Thank you for a great plugin! On my website, I’ve added the social icons to individual pages via the shortcode and via a widget. In both cases, the icons are pushed far to the right. See the bottom: https://completepla.net/here/

How can I make these icons show up centered or left justified on the page? There are no hidden styles in my text editor, so I’m confused as to why this is happening.

Thank you
