docker-machine start = Starting "default"... machine does not exist???


I’m having a very strange error and can’t figure out why.

When I run the command ‘docker-machine start’ from terminal I get the following error

Starting “default”…
machine does not exist

I’ll attach the screenshot, but from what I can see and the commands I’ve used, it appears that there is actually a machine called ‘default’

If anyone can explain to me where I should go from here? I’m at a dead end as I can’t even get the machine to start.

Thanks in advance.
