Carbonite Quest Waypoint Issue

[ConsPark]

I just got back into WoW about two weeks ago, and ever since then Carbonite's quest waypoints have been a bit flaky. Specifically, ones for old quests don't automatically delete themselves:

So every five quests or so I have to manually "clear goto" lest the map be practically unreadable. I haven't been able to come up with anything about this using the search or on google. Any ideas? And yes I am running the latest Carbonite.

Thanks
