Instead of popping of the jump just try coasting it. Some jumps aren't good for popping depending on the transition. And do you happen to have a narrow stance? I narrowed my stance to 23.5 from 25 (due to my limited stance options with a new binder) and I noticed I was washing out on my toe edge on my heavier landings. I ended up going back to 25 and it's much more stable. Just a thought.
