There are a couple different tabs, you might be looking at the wrong one. And you can definitely drop a quest. Click the ring icon on the bottom left of your screen and it will pull up all your current quests. You can right click the one you want to drop and then click "cancel". It might take a while before you can restart some quests, but for this one, it shouldn't be a problem.
