Custom Field Checkboxes

Hello.

I am trying to create some Custom Fields with Checkboxes but there seems to be something wrong.

Whenever i choose 'field_type' => checkbox the title dissapeares in the backend and the checkboxes are huge and looks really bad.

I have used the code from awesume support themselves and this is the only code I have added:

wpas_add_custom_field( 'my_field_draktservice',
    array(
        'title' => 'Draktservice',
        'field_type' => checkbox,
        'options' => array(
            'option1' => 'Waterproof',
            'option2' => 'Ursuit',
            'option3' => 'Viking',
        ),
        'order' => 1
        )

Can someone help me regarding this topic?
