Unreal forces me to spawnThirdPerson blueprint

I have created MainMenu scene with 3d content. I placed a camera where i need it.

  • Created a new GameMode to override default spawn, “Default pawn class” as a custom camera i made.
  • used this GameMode as the one in this scene inside “World settings”.

When I press play it is still spawn the ThirdPerson bluprint and all its compenents. it uses my camera, but i dont want unwanted content to be in the scene.

Dont understand how that works… please help
