If you have not rescued all the pokemon from the warehouse, that won't prevent you from using the levers. By being able to get in that new room, it means you have completed the warehouse mini quest.
I cannot see why the lever would not work, however. If it still doesn't work, can you come on the live chat when you are online and request for a content scripter? If I'm around I'll try to see what is wrong. If not, try to stay around the live chat as much as you can until a content scripter comes around.
