There's a problem with my skins rn, can someone help me out.

So like I was checking my skins out today and when I was looking at akali I couldn't help notice that my Crimson skin was missing and I couldn't see if the skins were bought yet. I checked other champions. All the legacy skin that I have are missing. I can use them in game but I can't find them in the store or the champions thing. Can someone help me out.
