Lyrics don't appear after upgrade iOS10

I recorded my voice on voice memos it's English vocabulary and grammar that I need to memorize before taking TOEFL exam. I put the lyrics on them to show when I'm playing to help me if I forgot and it's always work.

Then after upgrading to be iOS10 all of my lyrics never show. I checked on iTune it's still there, still in the Get file info > lyrics.

Let me know how can I fix it?

Thanks.
