If I control a Ketramose, the New Dawn, and on my turn cast Surgical Extraction on a target, if I exile multiple copies from the graveyard, Ketramose triggers once for each card exiled, when it should only trigger once.

I think this may be correct behavior. Surgical Extraction sends the cards to exile as you choose the cards which would cause Ketramose, the New Dawn to see each card individually. This is similar to how Marneus Calgar will draw you 5 cards instead of one with Season of the Burrow if you choose to make five tokens because Season of the Burrow makes the tokens one at a time as it resolves and not all at once like a Spectral Procession would.
