Some options can be set only after the listing is pblished.
After publishing you can use the "preview" option to view the listing from editing mode
You can set the "availablilty window" option temporary to "dates not available by default", to prevent people finding/booking the listing while you are still working on it.
Some options are set by default, check them all.
