Cannot install music data pack

I installed music data pack 2-3 days ago. Now I started Minecraft, but I haved Music: 100% but no music (Moog city 2...)! I headed onto marketplace to check, if I have it, but no. It was deleted or what? Then I installed data pack again, but in store, when I looked on music, it was not in my tablet. It's deleting or WHAT?!

 

Edit: FIXED!
