A problem with displaying quest objectives at mouse hover.

So I have this problem.

I have a quest for getting stuff from mobs.
Whenever I hover over or even target that mob (which should count to the quest), I only see the mob info, but not quest info, here is the screenshot:

However, that same account but different character, it works just fine:

I checked 'quest' and 'interface' settings, they are the same (or I just missed something?)
So essentially I want for all characters to have quest objectives displayed as on the second screen.
Please help.

P.S. Sorry, couldn't figure out how to insert screenshots right here, so there are links.

Maybe remove the Cache folder, but there's another problem with the first screenshot: the mob is level 1.

Yes this happends on some mobs in the game, After doing Loremaster and compleating over 3000 quests I can say that some few quests dosen't track the quest info. I don't know if its a bugg from warmane or if blizzard had it too but you will just have to read the quest text sometimes on those quests.

Thanks guys. Yep, seems like it works on other mobs.
