Ranked Team Ward Skin MIA

So, just recently I won enough ranked team games with my friends to be able to get the first reward; the Conquering Ward Skin. However, when I go to the shop to activate it, I find that it's not even there, EVEN THOUGH it says that I have unlocked it in the Leagues tab on my profile. Someone please help! If you have any information on the subject, I'd love to hear it. c:
