I know everyone is posting about losing photo stream but I am missing s bunch of photos from my collections section. It looks like they are there but just blank. I'm currently using an iPhone 6 but it's the same on my old iPhone 5 with iOS 8.

Any ideas how to get them back? I used recent backup from iTunes to activate/setup my 6.
