Problem builder settings. Loads the wrong scene

I watched a lesson - CREATING A SCENE SELECTION MENU. all done right, nor any no errors. When testing is loaded the wrong level. I have scene 0: as basic menu - start/options/exit. Scene 1: scene selection menu. Levels start with 2. Load on click the button of the first level - index in builder srttings is 2, index 3 for level 2 and 4 for the third level. Level 1 is loaded correctly, the level 2 is loaded correctly. Level three I did not create, I copied the Level 2 and changed a bit, just to see difference. How ever when loading these changes are not loaded, its the same scene as loading when I load level 2. Builder index arranged correctly, I even changed the "int" to "string" in the code and load the levels by full name, but all the same.
