Kayn Predator Boots Glitch

As you can see, even though I have enough gold and the components to buy Enchantment: Warrior, I can't buy it for 525 gold. This also happened with stalker's blade, where i was forced to buy it for 1000 gold instead of 300 like normal. Predator boots are also a blank square. This only seems to happen with Kayn when he is equipped with predator boots, haven't noticed it for anyone else. I did not have future market or any of those sort of runes. Please fix this as soon as possible, thank you!
