WPGlobus 1.5.8 does not support Custom Post fields

I do use the purchaised theme “Restinn” and it comes with cutom post fields that I can’t get to translate. Not even the {:en}english{:}{:de}deutsch{:} syntax workes. It’s printed as {:en}english{:}{:de}deutsch{:}. The sh_room_meta looks like this:

$options[] = array(
‘id’ => ‘sh_room_meta’,
‘types’ => array(‘sh_room’),
‘title’ => __(‘Rooms Options’, ‘wp_restinn’),
‘priority’ => ‘high’,
‘template’ => array(
array(
‘type’ => ‘group’,
‘repeating’ => false,
‘length’ => 1,
‘name’ => ‘sh_room_options’,
‘title’ => __(‘Room Information’, ‘wp_restinn’),
‘fields’ => array(
array(
‘type’ => ‘textbox’,
‘name’ => ‘price’,
‘label’ => __(‘Room Price’, ‘wp_restinn’),
‘description’ => __(‘Enter room price’, ‘wp_restinn’),
‘default’ => ”,
),

How to make custom post fields translate?
