Madreds and Grez's Spectral Lantern, and Wriggle's Lantern.

Hi, I don't know exactly where to put this, but once you open League, on your profile in the item sets section, it says when I mouse over madred's, Grez's Lantern, and Wriggle's Lantern that they are only not available on The Crystal Scar and Howling Abyss, shouldn't it also be not available on The Summoner's Rift? I'm just confused about this.
