[Help] Furnimatic Walkway fix? [Plus Emu]

Hi all just wondering how you fix the height of the walkway furniture from furnimatic.

I cant seem to get the correct height for the furniture.

If anyone can help it would be appreciated.

Shouldn't be too hard to fix this.
Search for the furni in your items table (or something like that)
Change the Stack_height / height / ... to 4 or something
Save your changes
update your furni in your client with :update_items or :refresh_items or similar
reload the room
Check if the height is right. (You might not be able to walk on it because it's too high. If so, teleport to it.)
If the height isn't right, change the hight to something higher/lower and try again.
