After completing the weekly heroic to get nine strange coins in bought the Achlyophage Symbiote from xúr. I then dismantled a pair of exotic gauntlets that turned you invisible when you get meleed I went back to Xúr and had him upgrade my new helmet only to my surprise I payed for nothing. What's wrong did I do it wrong or does he not upgrade it all all

Your Helmet was already the upgraded version. You said you had just bought it. So you wasted the shard and glimmer and exotic arms. I don't know why they allow people to do this but people fall for it all the time.
