SaveGame not working?

Hello! I know this is a repost because I have come across another error in my save game. My issue is that,I have a highscore variable, and if a player has a score greater than the highscore, the highscore gets set to that score. I have that blueprint running in user interface widget. So let’s say that the player had a last score of 100, and the player gets a score of 110. Then the HighScore will get set to 110. However, the highscore is still 0. I know for a fact that the score isn’t the problem because I used a print string and it outputted that the highscore is 0 and the score is 110. I have also left a download link to my project to figure out the issue. Thank you for helping me!
