Item is Opaque in s4s but not in game

Hi, this is my first time making an item from scratch and I finally managed to get it into my game to test if it had worked, but when I went into game the main body of the soap dispenser appeared clear/ had a cut away look to it. I have almost no blender knowledge or s4s knowledge past recolours so I'm sure it was something I did along the way but I'm not sure what, so any help whatsoever would be appreciated. I would like the body of the dispenser to be fully opaque.

here is a link to the package file and a screenshot of the item in game
