Custom sizes not showing in the crop modal

[juuga]

Hey, I installed MIC 1.08. I am using WP 4.0. In my active theme's functions.php I have the following lines added

add_image_size('small_carousel_thumb', 172, 97, false);
add_image_size('large_carousel_image', 870, 490, false);
add_image_size('large_feed_image', 570, 294, false);
add_image_size('small_feed_image', 276, 144, false);

function named_custom_sizes( $sizes ) {
    return array_merge( $sizes, array(
        'large_carousel_image' => __('Large Carousel Image'),
        'small_carousel_thumb' => __('Small Carousel Thumbnail'),
        'large_feed_image' => __('Large Feed Image'),
        'small_feed_image' => __('Small Feed Image')
    ) );
}
add_filter( 'image_size_names_choose', 'named_custom_sizes' );

However in the crop dialog I still only see the Thumbnail tab in the featured image crop dialog. How could I get the other custom image sizes to be available for crop. I am producing this issue on my local server running PHP 5.4.10.

I also tried this with the add_image_size functions inside the after_setup_theme action hook.

You probably fixed this but for anybody else having the same issue try changing false to true.

so now reads:
add_image_size('small_carousel_thumb', 172, 97, true);
