How can I delete all sapphire data on my apple TV so that I can set it up again - I made a few mistakes in the beginning

Most likely, what mistakes you made can be undone without having to delete data.
If you made a mistake on naming a movie or tv show, you can use the reset of import decisions: http://appletv.nanopi.net/manual/advanced/
If you accidentally imported a drive you didn’t intend, you can use delete collections: http://appletv.nanopi.net/manual/settings/
What mistake did you make?
