I’ve had the same problem on quite a few different woods. Maple, Cherry, Alder. I hate to say it, but when I gets bad enough some new planer knives usually takes care of it for me.(at least for awhile) As far as dealing with the damage done, I agree with John, high angle hand plane and/or card scraper should clean it up nicely.
