Arcanite Bladebreaker Dialogue Stuck

For the past 7 days I have been attempting to get the Arcanite Bladebreaker hidden appearance.

My concern is that Helgar’s dialogue is stuck on his initial greeting dialogue. I looked it up and found other dialogue options he has (Madseason’s Video 0:33)

I was told by a GM that he very well may possibly be bugged for me.

Does anyone have experience with this?
