WotLK Daily Quest bug - Icecrown (WOTLK)

[Timothybtw]

I've noticed a bug where every time I try to take on new daily quests, it already says they are completed and done, even though I just picked up the quests. Does anyone know how to fix this?

Here is a pic showing how it looks: https://gyazo.com/fcb27c18a6f6241776d5e115a4e246d3

If you already have the required quest items in your bag, the quest will automatically complete as soon as you accept it.
For example: in the Wintergrasp quest “Warding the Walls”, if you have 10 Enchanted Alliance Breastplates in your bag (because you abandoned the quest earlier and the items remained), the quest will instantly complete upon picking it up again.
Otherwise, you likely have a malfunctioning addon that incorrectly shows the quest as completed when you accept it . even though you shouldn’t actually be able to turn it in.

Got no saved items or such things, might be some sort of addon then. But i have tried to do these quests anyways but i dont get anything from them to complete it. Even if its items or kills etc.
