I have to unbox an item that I already was able to wear?

I had  a demo I was able to wear without havning to unbox it. A log in a month later and try the same item on and now I have to unbox it. Why is this

Probably because of this:

Once the all clear is given you should find the unboxed folder in your inventory.  If not , clear cache and relog.

My guess is you are unboxing the original boxed item. Maybe you have another folder in your inventory that already has the unboxed item? After I unbox the contents, I throw all my old boxes into a specific folder in my inventory so that I don't accidentally open them up again.
