Assuming you've used online licensing in the first container to login to MATLAB

This is probably due to the fact that the first container has not returned the license it has checked out before shutting down.

Could you try explicitly exiting MATLAB before you shut down the container? Does this help resolve this for you?

I am also having the same problem. I tried to remove all the images and stopped containers in case the license is still in any of them, but the problem persists.
