Intro level blueprints reset when i start the main level

i have two levels in my game and on the intro level (main menu) i have made a widget with buttons which open my main level (game). when i click on the play button which opens my game level it loads it and executes the game level blueprints (which plays a song and does some other stuf) but it also executes my intro level blueprints and because of that it hides my game because there is a widget in front of it. what do i do?
