Got a piece of bad gear

Hello, yesterday while running raids and depositing WB chest I grabbed a piece of gear from the WB vault only to have it after equipping going from usable gear to “reservist gear”. I have never done a change over to DH on this character. Furthermore it won’t let me get rid of the gear because it is current WB gear. have photos of the issue and it is still in my bags haunting me.

you just need to destroy it, if its got gear rank on it use gear rank transfer at blacksmith

Go ahead and post them.
Instructions for how to do so…
