How come my 15 levels say “redeemed” when I have nothing of what it says was redeemed?

I spent all my crystals to redeem 15 levels of the new set. Tried to redeem the 15 tiers and said “error try again later.” I played a match and went back to the rewards tab after the match and it said everything was redeemed; but nothing shows up in my collection that was redeemed?… Never doing that again.
