Itunes not seeing albums.

Since the upgrade for itunes on my Iphone 6, I have a couple of problems. I can see all and play all of my 487 songs in songs, but:

1/ When I go to Artists(IE: Il Divo, I have 11 songs over 3 albums, but can only see 2 of the albums to play, Anccora which I copied 7 songs from a CD doesn't

appear, it used to before the upgrade.

2/ Also in Artists, 80% of them show all the songs from the albums, so I can shuffle them, but I have some artists, where it only shows you the albums, not all the songs, so I can only play songs from one albums at a time, instead of a random shuffle of songs from any album.

It is really annoying me now, to the point, I just can't be bothered to listen to my music anymore.
