Echo knight kill does not count for spoken and unspoken if quest is not progressed

I had killed the echo knight in the crucible for the first time, however I am now unable to progress the quest without killing him again due to the fact that the npc interaction part of the quest was not at the state where I would have to kill him. I wouldn’t think this is a bug except for the fact that special dialog for the merchant npc in the crucible is still triggered.
