Lost iTunes Album

So one of my albums on my iPhone 6 was all messed up and there were songs missing so I thought that I would delete the album and download it again to see if that would help. After doing that I went into the iTunes store and I was not able to find it under purchased and "not on this iPhone" I also tried to look at the album in the store and it said I had already purchased it and it would not allow me to re download it. I also logged out of my iTunes and logged back in to see if that would help and again I was not able to find it to re download. If there is anything you could do to help me get my album back that would be great. Thank you.
