Bug with " The Coming Calamity Heroic Armour"

I just buy to another users two of this body armour, one with two augmentable sockets and the other with three.The first whit "Grants Skill levels: 19" and the other with 20.

When i use this armour and star a map this one disappears in my equipmet, few minutes later it reappears in the bag without runes and gems i loose all and i have to set up it again and repeat the process when start another map.

Is there any way to resolve this?
