Code styles are applied on a project level. There is no global setting. You can set a default style via Settings > Other Settings > Default Settings > [Template Project Settings] > Code Style Any new project will use that style.
That said... when you reformat you should get the styles you set. You need to verify that the configuration you created is set in the Settings > [Project Settings] > Code Style --> Scheme dialog. I seen some case where the default is actually reselected by mistake. You may want to double check the specific setting options in that scheme. Make sure the same code that is shown looks exactly like what you want.
Then run a code Layout reformat (Ctrl+Alt+L)
