Drupal 8.x

Hello,

I just installed Drupal 8+ I am a new user to Drupal . I then added added this theme http://demo.zymphonies.com/free-theme/professional-responsive-theme/

When I installed it , comes with pre-installed Social Media ICONS lined across the top of page. I would be happy to use a few and think they would look good there. However the Icons are not displaying properly as you can see on this screen grab of my site ;

Not showing with Chrome or Firefox.
PHP 5.6.30

So I was playing with content type and views,
And I deleted the content type but I forgot I added filter criteria in a view, with that new content type.
So it also deleted the whole view because it had relationship with that content type.

Isn't that little bit much?

I noticed it right away because it was my front-page view..
