How to remove Social Integrations message inside Discussions

Hello.
In "Settings" - "Social Integrations" I turned off all single share buttons, but the message is still displaying. Is it some function to turn it off or I need to do it manually by customisation?

Thanks.

Update:

This message doesn't appear in "simplistic" theme, but appear in "flatt", for example. After disabling all share buttons, need to edit "post.question.item.php" file and remove line with COM_EASYDISCUSS_SHARE_THIS_POST.

Thanks.
