This has happened to a few others in the past. The reason hasn't been pinpointed.
I'm assuming that you aren't getting a sub-quest to go talk to Valgard Goldenblade when Jotun is defeated. That needs to be done to complete the quest.
My suggestion would be to try again, doing each brother, one at a time. Defeat each of Jotun's brothers individually in their own areas. Then go and defeat Jotun, who should now be alone or with the minion. If that doesn't work, send in a ticket to Support.

That's right, I am not getting the quest to talk to the king Valgard or whatever his name is. I will try your suggestion.
