Where you register the field, can you check you have the sanitization_cb as per the example:

array(
    'name' => 'Cooking time',
    'id' => $prefix . 'cooking_time',
    'desc' => 'Cooking time',
    'options' => array(
        '5' => '5 minutes',
        '10' => '10 minutes',
        '30' => 'Half an hour',
        '60' => '1 hour',
    ),
    'type' => 'pw_select',
    'sanitization_cb' => 'pw_select2_sanitise',
),
