I just did a search in my ebook copy of White Night. "Rodriguez" appears four times. One is clearly a reference to Susan ("Ms. Rodriquez" hasn't left South America).
One is a reference to "Rodriguez's shield" in the duel in the Deeps. The other two are said by Molly when she's talking to Harry about things, and both are "Warden Rodriguez."
So clearly, in my mind, three of those are incorrect references to Ramirez, still present in my copy.
Guess the world, populated as it is with humans, is an imperfect place.
