Hi Chris, article top-right icons are from here:

we don't have yt share. and I don't even know if YT social share is possible.

To add extra social share code you have to edit template file:

templates\shaper_helixultimate\html\layouts\joomla\content\social_share.php

about that (artile top-left)

it was installed/added by you, social plugin probably. It's not from Helix, and I can $10 bet to prove it.
