Unsolved main quest

[brickfriends]

Hello everyone,
I have got a problem with the last main quest in the main game. I got the quest: go to the north-east island. So far so good. I played through the whole game, the sailor took me to the island, I defeated the shaman boss and saved the world
But in my questlist, the quest "go to the north east island" is still open. When I visit the island again, the shaman boss is still there, but invincible : How can I delete the quest in the list, it is quite annoying. The shaman boss can walk over the island till death, never mind.

Please help

So you already finished the game and saw the end sequence? Then you can nothing to do, probably it's just a bug. Don't care about it. : )
