Pulsefire Ezreal Glitch

So here's where I found this thing out. I just got myself 3 $10 cards, hoping to find something exquisite for myself, and thought 'Might as well get the last ultimate to get for myself.' and I done did it, until I reached a problem. I do own Ezreal, and I have 2 skins for him already (NottingHam and TPA). I had the options 'Champion owned' and 'Not owned' on (as always) and I switched it to the 'Ultimate' setting. Thing was, It wasn't there! I just wanted him man. Q_Q. But then came the even stranger part, I checked up on his champion profile, it said 'Unavailable.' But then came the twist, I went back to the store just to check back, I scrolled down, ***AND IT WAS THERE, PURCHASABLE! *** Riot I hope you please fix this so then I can make sure I can have all three Ultimate skins next time, please and thank you.
