The immersive titles in my cascade story won't save to the black font color option. I have tried over and over to save them and they always revert back to the default (white font color). I have two immersive sections that this is happening in. They are two separate maps but in both sections they copy through, each having 6 sections with different layers turned on and off. I did create this story before the new release, wondering if maybe that has something to do with it. Is it a bug? Am I doing something else wrong?
