This made me chuckle when it popped up in my email. Since you lightened my evening, let me see if I can help you...
Docker will name containers with random snake case 2 word names if you do not specify a name yourself.
This container was created from a command and not through the unraid UI. Perhaps you have a user script or something that executes a "docker run ..." command?
If you enable the advanced toggle at the top of the docker page you will get more info on the container. You should be able to see the docker image used and that may give you a hint as to what it is.
