NPC quest indicators invisible

Describe the problem. Be as specific as possible!:
Availible, in progress and completed don't always show over NPCs. It disappears and you only see their text they spout every few seconds even though there should be something else there. [this is real obvious with repeatables, ex. Lita Lawless's quests]

Can't screenshot at the moment, will later

Click your quest window, go to available, and click "View All Quests"

Oh what the pineapple. Does it do that automatically [change to "only my level"]?

No it doesn't. You have to do it yourself.
