Duplicate mesh appear on loading from desktop

[Gokkuness]

Hello, 

I've got a problem with a mod i ported to sse. The head piece replaces whole the head (slot 30). When equipping it in game it works fine but when i save, exit to desktop and reload a duplicate of the headmesh appears on my character's head and stays there even if i unequip the head piece. Sometimes when i load the save a random mesh of an object present in the cell appears on my character (bottom half of a chest, a table...). It's as if a mesh is missing and the game replaces it with a random mesh present in the cell. Can someone help me with this issue please?
