Saving integer + integer to Save Game not working

I’m simply saving an integer + integer to increase score in to Save Game. If I print string it keeps showing 1 for every hit. For some reason integer + integer wont increase score. If I do exact the same thing with Game Instance the ++ integer works fine. What it strange that for the first hit on trigger box it increases score from 0 to 1 or what ever number I put in integer (4) integer for example it will show fine but not for the second time the trigger is hit. Does trigger box needs to be reset after every hit? How ever I don’t need to reset anything when casting to Game Instance. If any one can help it would be super great!! thank you!!
