Hi, I am having trouble finishing the above quest.

Character: Onikami Mukyoku
Class: Lancer lvl 22
World: Behemoth

1. I got the quest from Owen,
2. Walked to the Quest Zone,
3. Click on the quest, but there's no "Initiate" button to start the quest, and there's no "Abandon" button to abandon the quest.
4. On Objective, it just says "Complete Owen's trial guildleve"

Been a couple days now. I've reported the bug in the game itself and was directed to post my problem here. Hope someone can help.
