Issues with Snow deform

hey everyone, so on another site i went through an entire tutorial about Snow Deform, followed it to the letter, issue is it only works on the one level. as soon as i make another level and add the deform to the landscape, i play in editor and the deform around the mannequin is a perfect giant square rather than perfectly around the feet and legs, im attaching some photos of whats happening and the BPS, if anyone can help me out id be extremely grateful!

it should look like this
