Hello, @AnimalShop,
Thanks for explaining your issue in detail, Actually that is the WordPress Media Library and our theme does not have any influence on it, that is the default functionality of WordPress and there is no option to change its behavior in WordPress for now, so this requires extra Customization.
If you want paid Customization services submit a customization request to WPKraken team.
Thanks for your understanding.
Regards 8Themes Team.
