wp_editor and WPAlchemy messes up tags when updating

when using wp_editor, I paste my text in the visual editor. If I switch to HTML editor, all of my tags are there. So far, no problem. When I update the thing, all of my tags appear in my visual editor and in HTML, they become something like :

<p><strong>

If I update again, the tags appear on my page. So i’m stuck in editing my text only one time. If I update more than one time, the tags appear and everything gets messed up.

Anyone got a clue of what’s appening?

I’m using that line to create the wp_editor:

<?php $metabox->the_field('shortText'); ?>
<p>
    <label for="<?php $metabox->the_name(); ?>">Text</label>
    <?php wp_editor($metabox->get_the_value(), $metabox->get_the_name(), $settings); ?>
</p>

Thanks!

EDIT:

The problem is with

$metabox->get_the_value()

It parses the code with the tags, wich then messes up everything.
Is there a way to parse the value in the HTML editor and not the visual editor?

And then the function get_the_value();
