Aminatou's Augury doesn't work properly when cast multiple times in a single turn

Aminatou's Augury 6UU Sorcery
Exile the top eight cards of your library. You may put a land card from among them onto the battlefield. Until end of turn, for each nonland card type, you may cast a spell of that type from among the exiled cards without paying its mana cost.

When cast repeatedly on the same turn it remembers which card types you cast off the previous Auguries and won't let you cast those card types on subsequent Auguries.
Example line: Aminatou's Augury -> Mnemonic Deluge (off the Augury), recasting Aminatou's Augury three times -> can't cast sorceries off any of the three additional Auguries.
