Good, you are on the right path. Indeed, we get uncountable hit (in classical QM) on the screen, but the SWE implies that when you look where the hit is, you only entangle yourself which the hit, so there will be uncountable many AG each saying, but the hit is unique, like the W guy says that he sees only Washington.
