Nostalrius Begins - Quality wow vanilla realm (1.12)

I want enchant my chest but clicked wrong so the robe was "buggy".
i reconnect and after that i cant put the robe in my bad and i cant delete this robe.. everytime comes the message "Already looted"
need help!

Did almost the same, disenchanted some green bracers while they were in bank slot. Now after every loadingscreen 2 Illusion dust appears as they usually do but I can't loot them... Very annoying.
