The second one is just annoying, but for the first one, the best thing to do (since for some reason holding forward and pressing AC isn't working) is just be picture perfect with your DP motion. Do NOT do what everyone does when doing DPs in doing F, QCF. You HAVE to do a perfect DP motion, no more, no less (obviously no less otherwise the DP won't come out). If you do a perfect DP motion and then do QCF+AC, it won't register 2 QCFs. It's a hard practice especially if you do F, QCF like most.
