LYRICS BUTTON ARE MISSING IN MUSIC APP

I've been struggling fixing this error for the past 2 weeks but still haven't got anything comes up. Since earlier, like many years ago, I'm one of a kind that adding lyrics and artworks manually using iTunes then sync it with my phone. But since I'm using iOS 11.2, the lyrics button is missing, like gone, all gone. But the artwork are still there after syncing up with iTunes. So, I still can't figure that out. In the past, to view the lyrics is quite simple, you just have to tap the artwork. Please dont make it complicated for the users. I really like it when it simple and easy to use. It's too bothering when you have to open lyrics in Safari or using third party app like Musixmatch. This is why I go for iphone, one of its specialty is you can add the lyrics. Come on now.
