To Hide Social Icons:
- Go to template manager select template styles (Remember you have to do the same changes in all squick template).
- Under Basic tab scroll down and you'll see Social Icons, Select hide.[see attachment]
And for editing, there are few icons whose default values have been set through the code. You have to remove it from template.xml is you don't want them to show.
Although we have fixed that and will release in our next version.
