checkbox list labels

In example on site (https://metabox.io/docs/get-meta-value/#section-examples) you have this:
$interests = rwmb_meta( ‘interests’, ‘type=checkbox_list’ );
echo implode( ‘, ‘, $interests );

I have
‘options’ => array(
‘acustic’ => ‘Акустика’,
‘halfaсustic’ => ‘Полу-акустика’,
‘electric’ => ‘Электричество’
),

For me in front end it display value (acustic, halfaсustic, electric), but i need labels (Акустика, Полу-акустика, Электричество)
