Floating Trees with new tree feature

I have made two custom trees and added them to my mod as features since the last version of MCreator added the tree/structure feature. Since then I have been having difficulties trying to fix the big problem where random trees placed just float in the air and don't stick to the ground, even though I made a procedure for them to specifically spawn on a type of block. Anyone else having this problem and can it be fixed someway? I feel like I have tried everything, from watching youtube videos to reading topics on the forum and everything... Here you have a look at my tree feature and the result:
