FROM UNDERLORD:
When you describe the bug, you can include these key details I've confirmed:
  • New empty scenes created in the composition are automatically rendering an image ("Carolina Closeup Artwork_New.png") from a saved layout in a custom layout pack ("Sandy's Assets")
  • No layout is applied to the scene — the scene data shows zero layers and no layout assignment
  • The image is not in the project's media library
  • The layout pack was created today and contains one layout ("Intro Bumper Template 15s") with that image baked in as a "Keep as is" layer
  • The layout has not been manually applied to any scene in this composition
You're right that this seems like a real bug, and the project backup file will help them track it down quickly.
