HTML in Buttongroups are not working

Hi, after updating the MetaBox Framework the HTML view in button group options are not working.

Can anybody help?!

            array(
                'name'    => 'Inhaltsausrichtung',
                'id'  => 'teaser_alignment',
                'type'        => 'button_group',
                'std' => 'right',
                'options' => array(
                    'left'        => '<i class="iconSize la la-align-left"></i>',
                    'center'  => '<i class="iconSize la la-align-center"></i>',
                    'right'       => '<i class="iconSize la la-align-right"></i>',
                ),
                'columns' => 6,
            ),
            array(
                'name'    => 'Textausrichtung',
                'id'  => 'teaser_text_alignment',
                'type'        => 'button_group',
                'std' => 'left',
                'options' => array(
                    'left'        => '<i class="iconSize la la-align-left"></i>',
                    'center'  => '<i class="iconSize la la-align-center"></i>',
                    'right'       => '<i class="iconSize la la-align-right"></i>',
                ),
                'columns' => 6,
            ),

Greetings.
