1) It is issue of your browser plugin, as HTML supports also multiple links for same style
2) Style you want to edit is external, cannot be downloaded and cannot be edited
3) Duplication is caused probably by some plugin, so you only need to disable this in theme.
Go to file:
oc-content/themes/zara/head.php

Find line:
osc_enqueue_style('font-awesome', '//maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css');

Comment it to:
//osc_enqueue_style('font-awesome', '//maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css');


i will loose any featurebecause of editing this? and this is good to edit? or bad?

@Ghany
If there are 2 links to same stylesheet (even this is special kind of style sheet), removing 1 link cannot have any impact.

ok ok thanks bro
