Why do the structures i generate keep spawning inside of each other

im trying to generate a village with custom blocks/ procedures (i have watched 15 tutorials on jigsaw blocks and still cannot get it)

i have used the tutorial to do that https://mcreator.net/forum/101088/how-create-structure-will-be-generated-if-using-jigsaw-blocks?page=0

however for whatever reason the houses i made generate inside of each other and ive tried over and over to fix this however nothing i do seems to fix it.

Any way i can fix this?
