Social media icons can be hidden using the Show/Hide Elements feature--the same as you would Show/Hide other Elements in your StickyAlbum.  

Note: The video shows how to hide icons in the Classic Style StickyAlbum template.  Each template has the icons located in a different Section, but the process is otherwise always the same.  Social media icons will most often be found in the Bio Section or the Promo Section of the Folio.  You will need to expand the section by clicking the triangle next to it to show the icons.

Social Media Icon Location By Template - don't forget to expand the top-level section (listed first) to see the icon section. Not all tempaltes include social icons.
