Going backwards/staying at the same step in learning steps instead of progressing and graduating

Hi everyone. I was hoping someone could offer insight into what I may be experiencing here. I’ve been using Anki for over a year and a half and have never experienced anything like it. My cards are starting to build up quickly because the cards aren’t progressing through learning steps/graduating and it’s getting a little overwhelming to do every day on top of study for class. I really don’t want to have to restore from a backup and lose my progress :slight_smile: Any help would be greatly appreciated. Thank you!
