I bought the mannequins from the cash shop yesterday they are missing the middle textures and the pieces you can see are distorted. I’m very sad about this I really like the mannequin in the photo. This is not what was advertised it looks really bad. I’ve also included the original cash shop photo. I play on steam.
It’s just a bug, I’m sure they will eliminate it soon.
Rule 1 of the Ferengi Rules of Acquisition states,
“Once you have their money, you never give it back.” 
Like @Ko6ka said, its just a bug.
