Answer 1

You can remove all dangling images with docker image prune .

Why is this happening? I can't really think of a good reason. What actions lead to this?

Answer 2

'Docker images' command will display all the images including the old versions. That's default behaviour. However, you can use filters to list specific images, I cannot see any direct command to list only latest images.

You can also try like this, For example, docker images java:8 which will give you the image of java with version 8.
