Disable – Randomize suggested headers and other options

Hello,

I’m making a wordpress theme but I can’t figure this out.
Using this code in my functions.php:

$headerimgs_args = array(
	'default-image'       => get_template_directory_uri() . '/img/logo.png',
	'uploads'             => true,
    'random-default'      => false,
	'header-text'         => false,
);
add_theme_support( 'custom-header', $headerimgs_args );

Only the “Randomize suggested headers” keeps showing?
I want to only disable that option as you can see but it doesn’t work. what am I doing wrong?

Thank you
