I received a HP on one of my aways, still ended up matching. I am not sure if it was actually on my transcript but I was never asked specifically about my grades and I was told on multiple interviews that my letters were good. At some places attendings are supposed to give out a certain amount of H, HP, P, etc I think that was the case at my away and that is why even though I got that grade I was still given a good letter. Hopefully that is the case for you all as well and it doesn't end up affecting your application negatively.
