Problem with new game

Hi. In my game i have problem with new game option. I`m using PlayerPrefs.DeleteAll(); and after that i set new values for some static variables. But it`s dosen`t work if i don`t get off editor, and play it again. I must add something to have reload after new game? Now i`m loading new scene after use new game but it`s dosen`t work if i don`t reset editor.

 

This is really unclear

 

Ok simple version of problem. Push button Play in Editor->Click new game (which have function PlayerPrefs.DeleteAll() and some set variables in it and function to change scene on function end) -> nothing happends, only scene is changed, but all data are the same.
Click button "Play" in editor again to stop game -> Click button "Play" again to star game again -> all data are cleared and game work with reset data.

I want to have reset data without pressing "Play" again

 

Just do PlayerPrefs.DeleteAll() again.

 

But why this isn`t working on the first time? If this works i should can use my new game function after new scene loaded Effect should be the same.
