Well with that one, you know, Andy was in the room with the Twin Peaks Sheriff's Department looking for clues about Cooper's shooting and he went to reach for the note, and hit his head and knocked the note under the bed accidentally and then forgot and went to the bathroom. Sometimes you hit your head on a plank and find a hidden stash of boots and cocaine and sometimes you hit your head and knock Audrey's note under the bed. Win some, lose some.
So, yeah, it's Andy's fault.
In all seriousness though, all the clues and suspects in Season 1 are red herrings because, at that point, Lynch and Frost had no intention of actually solving the mystery, so the clues really aren't that vital and by throwing in the high strangeness of inhabiting spirits and dark magic into the mix it pretty much takes a deus ex machina (Laura telling Cooper in a dream and then him suddenly remembering this) to actually solve. Definitely not your traditional TV murder mystery, though I can see how watching it now for the first time with no prior knowledge might lead one to try at first.
But the blood type thing *probably* was a gaff in that they forgot they had that in the Episode 5 script, but it's not completely contradictory.
