Elementor media control is not working on live website (Works on editor)

[davidxoma]

I have Media control code in elementor. This control is about to show default image on posts archive when the post has not featured image. Everything works perfect on left side editor, when I choose default image, posts without featured images displaying choosen image, but when I open live website it shows Elementor's default image, placeholder.png (as you see in the code its a default image if did not choose anything). Did print_r the $settings variable and image_def's url is blank. For some reason image that I choose is not saved for live website. Have no idea what is happening

$this->add_control(
        'image_def',
        [
            'label' => __( 'Choose DEF image', 'plugin-domain' ),'type' => \Elementor\Controls_Manager::MEDIA,
            'default' => [
                'url' => \Elementor\Utils::get_placeholder_image_src(),],
        ]
    );
