Multiple Elementor "Group_Control_Background" control label is not working

Question

I need 3 background group control on Elementor custom widget. So, I am using this:

$this->add_group_control(
    \Elementor\Group_Control_Background::get_type(),
    [
        'name' => 'background_active',
        'label' => esc_html__( 'Background Active', 'plugin-name' ),
        'types' => [ 'classic', 'gradient', 'video' ],
        'selector' => '{{WRAPPER}} .navigate-master ul li a.active',
        'default' => esc_html__( '#ffb200' , 'plugin-name' ),
        'condition' => [
            'nm_nm_title' => '',
        ],
    ]
);

$this->add_group_control(
    \Elementor\Group_Control_Background::get_type(),
    [
        'name' => 'background',
        'label' => esc_html__( 'Background', 'plugin-name' ),
        'types' => [ 'classic', 'gradient', 'video' ],
        'selector' => '{{WRAPPER}} .navigate-master ul li a',
        'default' => esc_html__( '#ffb200' , 'plugin-name' ),
        'condition' => [
            'nm_nm_title' => '',
        ],
    ]
);

$this->add_group_control(
    \Elementor\Group_Control_Background::get_type(),
    [
        'name' => 'background_hover',
        'label' => esc_html__( 'Background Hover', 'plugin-name' ),
        'types' => [ 'classic', 'gradient', 'video' ],
        'selector' => '{{WRAPPER}} .navigate-master ul li a:hover',
        'default' => esc_html__( 'yellow' , 'plugin-name' ),
        'condition' => [
            'nm_nm_title' => '',
        ],
    ]
);

You can see that I have used a unique name and label but I can't see the different label on the widget sidebar.

Can you tell me why?
