Hmm... I guess it is a little strange, but I think these objects are a bit differently set up than normal imported ones. I'm guessing in the actual Basic or Ultimate version of Lumion, you wouldn't need to edit too much.
In this case, I just suggest importing from google warehouse or something else.
The material set is somewhat limiting, but you can import images for most things, so you should be ok for the most part.
