XPS 15 9500, lid is not tight close when keeping notebook vertical

Hi all,
I got my new XPS 15 a week ago and I see something that bothers me.
When I keep the notebook vertical the lid will open easily and it seems like there is no magnet that keeps it closed.
My concern is when I put it in a bag and go for traveling it will open and close a lot during movements and will damage something, I will attach pictures so you have a better idea of what I'm talking about.

Is this by design or only I have this problem?
