Need help with bodyslide

[c6222848]

Hey everyone, 

 

So i download the Banded Iron bikini ver.2 on nexusmod :http://www.nexusmods.com/skyrim/mods/69631/?

And i try to use Bodyslide outfitstudio to merge the parts of it into a single armor. then i run bodyslide and create the nif files.(i can see the shoulder part  in the preview and nif file.)

(i used the CBBE HDT body in the app as baseshape)

But when i go in to game and get that armor, i can only see the knee armor ， the shoulder and spine part are missing?

what did i do wrong?
