Quests Don't Go Away

I am having trouble with Abysmal and the quests getting "stuck" in the quest log. I have just completed the Valor quest, got the arkaine armor but the quest remains in the log. I previously played this mod and other quests got stuck as well - The Anvil, Black Mushroom. Is this something that can be fixed or will I have to look at these completed quests through the end of the game?
