Button Error

I’ve a problem with the button shortcode. The plugin generates this shortcode:

[button style="btn-primary btn-lg" icon="glyphicon-bold" align="left" type="button" title="Button"]

But the code that appears finally is:

<a href="" class="btn btn-button "></a>

As you can see, it doesn’t have the title, classes, icon, etc.
I don’t have any other plugin installed and other shortcodes works fine.

Thank you very much for your work!
