Quest Pushing to the limits

My durable information securing container is ilvl 694. I picked up the quest Pushing to the limits. After finishing this quest I wanted to put it in but got the next error Turn in for ‘Pushing to the limit’ failed. This quest’s unique reward already excist in your inventory. Remove it to complete this quest. The Titan memory card is indeed in my inventory so I tried to trow it away but I get the message this item can’t be destroyed. Now I’m stuck and can’t level this item to max. I made a bug report but the past tells me nothing will happen to help me out from Blizzard. Has anyone else a solution? Discarding the quest and do it again is no use because I still have the item in my inventory.

Right click the card then click on your belt (it works like an enchant).

Once it’s consumed you’ll be able to turn in the next quest.

That’s too bad. It’s likely that you’ll replace the slot with a patch item sooner than they’ll get around fixing the bug.

Sad to say but overcharged delves are going away in two weeks.

This solved it, thanks.
