Dear Hassan,
I have opened a ticket for the developers to register this string for translation. Meanwhile, have you tried with something like this?
[wpv-control taxonomy="manufacturer" type="select" default_label="[wpml-string context="mytheme"]- Any Manufacturer -[/wpml-string]" url_param="manufacturer"]
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Caridad
