Pro site, free trial again....

Hi, there is something i don't understand there.
After upgradig to 3.0.9 i have tested free trial and end of subscription process, to see if premium themes and plugins were removed, and it was working.
Now i see my users who have premium plugins after their 7 days free trials, so i tried with a new account, and it's not working anymore.
Premium themes and plugins are not deactivated.
I don't understand what happened...
