Problem with GP Social Settings and remove overlay image

Hello,
first of all, sorry for my bad english. I'm Italian. My name is Anna.

Like topic title, I've two problems.
1) I don't know how to set the GP Social, I want set "title + short url + twitter name user" and than "share", I want to display "Follow us on twitter" button.
I should translate di "standard massage" in email and whatsapp share.

2) I need to remove the big pic that appear in all single post. I don't talk about the small featured image but the big one set in "page-hero grid-container grid-parent overlay" (overlay image).

Searching in the forum, i find this code:

add_action( 'after_setup_theme', function() {
    remove_action( 'generate_before_content', 'generate_featured_page_header_inside_single', 10 );
} );

but when i try to add it in "single.php" or in plug in Edit Snippet, I do not solve the problem! The overlay image stell here.

every suggests are overwelcome!

Thx,
Anna

ps.: I'm using premium.
