Is there an easy way of clearing unwanted published items?

Looking at your data, you have two documents of type siteSettings with different _id values:

1. "932ebb41-cf8d-463d-9ad9-6e4c88588b54" (created first)
2. "siteSettings" (created later)

This is a common issue when setting up singleton documents - you've accidentally created multiple instances of what should be a single-instance document type.

To fix this, you need to delete the duplicate document. Here's how:

1. Go to your Sanity Studio and navigate to Vision (the query tool)

2. Run this query to verify which document you want to keep:

   *[_type == "siteSettings"]

3. Delete the unwanted document (likely the first one with the UUID). You can do this by:

   • Finding it in your Studio content list and deleting it manually, OR
   • Using the Vision tool with this mutation:

   // Delete by ID
   sanity.delete('932ebb41-cf8d-463d-9ad9-6e4c88588b54')

Based on your data, you probably want to keep the second one (_id: "siteSettings") since it has your actual content (name: "Amy", website, etc.) and delete the first one.

To prevent this from happening again, configure your siteSettings as a proper singleton in your sanity.config.ts:

export default defineConfig({
  // ... other config
  schema: {
    types: schemaTypes,
    templates: (templates) =>
      templates.filter(({ schemaType }) => schemaType !== 'siteSettings')
  },
  document: {
    actions: (input, context) =>
      context.schemaType === 'siteSettings'
        ? input.filter(({ action }) => !['duplicate', 'delete', 'unpublish'].includes(action))
        : input
  }
})

This prevents creating additional instances through the "New document" menu and removes dangerous actions like duplicate/delete from the singleton document.
