Cannot complete the task "Complete "Enhance your favourite gear!" "

I completed that client order before I got the tutorial to complete it and now since i already completed it I cannot complete it again and it does not register that order as already completed.

That orange marker is pretty annoying and I'd like to get the rewads for these quests, anyone knows how to solve this?

Bump because I'm experiencing the same issue.

EDIT: Figured it out, I think. Talking to the ARKS person and receiving the rewards for completing the quest seemed to clear it.
