Bugs with Pokemon Unbreakable Ties 4.9.1 [ HELP NEEDED ]

After not opening the game for a day, the save file I created with Nuzlocked was changed to EASY? I can't play on Easy, I don't like that. I was on my second attempt in Hard mode or on the other save file in Normal mode. Both were switched to Easy mode separately… Is there any way to fix this so I don't have to start over again? You can see in the pic that they both reset to easy

Any others had this experience, when yes did some of you fixed it? I am so disappointed i wanted to play today 🙁
