Both WebGoat Docker and the Jar forgets my user registration.

Docker seems more stable so that's what I use, but when I shut down my VM and then boot it up again and run the Docker, - Webgoat "Forgets" my login even exists. It says "Invalid username and password" Which means I'm forced to register again and I lose all my progress :( Is anyone else having this issue, is there a fix? It's really is annoying.
