I would think one can only see what Hashem allows him to see. For whatever reason (maybe it was a nisayon I really don’t know) the chozeh was supposed to disbelieve this Jew and he didn’t. Or maybe this was the Ratzon Hashem that for whatever reason there should be a “fight” between the 2 of them. If you know the stories about the early Rebbes you’ll understand what I mean. Dont over analyze that aspect of the story.
