Accessing ALevelScriptActor in the editor

so… I have a custom LevelScriptActor from wich I pull Data via Interface

however, when I’m in editor the Data seems to be from a default one although I edited the LevelBlueprint.

I getting UWorld->ULevel->ALevelScriptActor then Cast->MyLevelScriptInterface

Is there a checkbox in the project settings that makes LevelScriptActors presistent?

what is the correct way to accsess ALevelScriptActor in the editor environment?
