Preselect dropdown from GET

Hey guy,

i updated my WordPress an Contact Form 7 but now my preselection for a Dropdown is not working anymore.

The link to the form was: http://www.mysite.com/kontakt?person=Mark

The code inside my Form was:
[select* adressen id:ankommen “Mark|mark@mysite.com” “Tim|tim@mysite.com”]</p>
[dynamichidden hiddendefault “CF7_GET key=’person'”]

But now, it´s not working.
Any idea?
