Itunes Store

Okay, I’ve purchased a few music albums and singles on the iTunes Store right but I deleted them from my Apple Music library for some reason right and now I can’t seem to re add them to my Apple Music library. I tried repurchasing the singles and albums so it can reappear but it won’t allow me. It tells me that said album/single has already been purchased but it’s not showing up in my library nor in the “More” purchased section in the ITunes Store. Can someone help me with my problem? I hope I’m clear in explaining my situation, if not I’ll clarify. Thanks.
