Item Sells for an Additional Unique Prophecy Wand Rewarded me with a Rare wand

I started working on a Prophecy Wand ilvl 70-72 (Cannot remember) and it had the crucible passive Item Sells for an Additional Unique Prophecy Wand. After selling the wand I received a rare wand instead... During the sell it did show a item box so it gave me one but imp quite bummed I did not get a unique. Would be nice if I got the void battery I was expecting :(

If its a bug plz fix

same happend to me
void battery is the only unique prophecy wand so i was really excited but i only got another rare prophecy wand that is really shit
