Share This Entry Icons

I am using a child theme.
I pasted this code in functions.php of child theme as advised:
————————————————————————————
add_filter(‘avf_default_icons’,’avia_replace_standard_icon’, 10, 1);
function avia_replace_standard_icon($icons)
{
$icons[‘standard’] = array( ‘font’ =>’entypo-fontello’, ‘icon’ => ‘ue915’);
return $icons;
}
————————————————————————————-
I then installed, activated and set the plugin I wanted but new social icons appear with the old social icons remaining where they were.

How Do I (i) Remove the old social Icons and leave only the new social icons?
(ii) Push the new social icons to be UNDER the title “Share this Entry”
(iii) Use image in place of “Share this entry”?

Is there anything I am doing wrong?

Thanks for your response.
For those who will need help on this, this is how i worked round it:
>>Searched plugin that meets my requirements and installed it,
>>Uploaded image for background and set top margin using CSS,
>>Disabled “Share Share this Item” in WP Dashboard > Enfold Child settings.
