How do you get rid of "New Task! Dread Ring Campaign"?

icebear · January 2018

I do have a question that no one seems to be able to answer. For about 2 or more years now I have had this arrow on the upper right of my screen. I click start button & the same arrow is on the “Special Quests” under the Quests tab. Clicking the tab it says “New Task! Dread Ring Campaign”. I click that & just says goodbye. Why is this? I have completed that campaign long ago. Any clue why the arrow & task will now go away?
