Music categories are missing while singing

@CGrant56 Thank you, but I know how it relates to other instruments. Apart from all the other instruments, I'm just talking about singing on the microphone. I could already sing these categories, but they just don't appear to me. The level of ability is high enough, it can't be. It just doesn't update and so I'll never be able to sing other categories, no matter what level. I think it's a mistake from the game that I don't see anything new at which level. After all, it's on the board myself that I unlocked the categories.
