I have myself experienced plenty of Carbonite issues, and what I can say about them is, live and learn. Due to my experimenting to find solutions to various issues and non-issues with Carbonite, I've become so knowledgeable about the workings of the addon I'm regularly taking time to provide assistance on this forum.

Your issue sounds like, to me, one of the round buttons in your Quest Watch window having been toggled off. The Quest Watch window is where your watched quests are listed, and at the top of that you have a bar with some buttons. Four of these are round, and the left-most of those control showing colored zones on the map for where you have quest objectives to complete. It toggles between green (show) and dim (do not show).
