Mandachord songs not saving

[(PSN)Ranger-_184]

I just noticed this today. After I was done editing some mandachord songs, I hit save and exit. When I tried to reload them later the changes were not saved. They just reverted back to a previous version. I fixed them, made 100% sure I hit save and exit, and immediately reloaded them. The changes still did not save. I tried reloading a third song, hitting save and exit, and reloading it again only for it to immediately revert to a previous version. The only other thread I have seen about bug is from 2017. I don't want to touch anything else because I am afraid of losing more changes. Is this happening to anyone else? Please fix this.
