Vafpress bypass the theme language strings

[webselfsrl]

Hello,

we have problems to translate the strings of Vafpress options/meta.

Ex. If we have a field like this:
array(
'type' => 'textbox',
'name' => 'title',
'label' => __('Title', 'my_textdomain'),
'description' => __('Leave blank to disable the section header', 'my_textdomain'),
),

In our .po file we see these 2 strings ("Title" and "Leave blank to disable the section header")

We translate them but in the options they remain in english.

It seems like it would be cached or our language string can't reach them..

Maybe am I doing something wrong?

Thanks!
