Parassitism 3/5

I've encountered two tyoes of "bugs" in the "parasitism" mission(3/5). in once instance, after collecting the sparkleaf, the objective didn't update to show "1/3" as completed. in other sessions, after collecting the sparkleaf, the game wouldn't let me place it into the container to craft the item; it gets stuck at 2/3. i've tried about ten times, both in solo and trio modes, but nothing works
