How do I stop structures from generating inside the terrain? (1.18.2)

So imagine this, You go onto MCreator, Put a structure into a game, Put void structures all around and inside the structure, Make it spawn on the ground, With where it stops is on the first block stopping its motion, Have it ignore only structure blocks, And you're excited to see your very own structure you just made, You spot it... But it's surrounded by dirt, And is also filled with dirt, And that happened to me.

How do I fix this issue?
