every survey question that appears in a survey that has ever been added to that project (questions from deactivated survey campaigns will still be shown)
every metric (progress tracker and outcome) that has been added to the project
You cannot remove these items from the default survey

The tick box Display each project’s default survey form is shown at the top of the Manage Surveys page
