Can't import tiled landscape on world composition

As the title says, It just doesnt let me click import. Even If i already had levels AND REMOVE THEM BEFORE ENABLING WORLD COMPOSITION it doesnt do the auto search thing for the leves. World composition is just not working please help.

This panel on your screen shot is for importing landscape as different tiles, not looking for levels in your project. Btw, this is correct way - make landscape heightmap tiles, then import it to world composition system. World Composition User Guide | Unreal Engine Documentation

If you want to add levels from project, click Levels/Add Existing.
