Saved cloud songs not displaying in my library

Hi guys. I have saved numerous songs from an album to my library in the cloud (not downloaded), about 8 of 12 album songs. When i go into that album that ive searched for through my library, I can only see three of the saved songs displayed. When I click show complete album I can see all eight songs saved to the cloud, alongside the ones i hadn't saved. This happens across my iPad and my IPhone. Why aren't all the songs showing? Really annoying!
