Importing mcworld in the Bedrock Edition editor will automatically turn it into a project, but not the other way around.

When the minecraft preview in editor mode is imported into .mcworld, minecraft will automatically convert it into a project, but in normal minecraft preview the game will prevent players from importing .mcproject

Expected behavior:
1. Unable to import .mcworld file in editor mode
2. You can import .mcproject and .mcworld in any mode, and the game will automatically convert

What actually happened:
1. You can import .mcworld in editor mode
and unable to import .mcproject in normal minecraft preview
