I am already meet the requirement for the curious badge still it is showing in list. It is bug or something i missed?
See this answer.
The condition which you need to meet to achieve this badge is :
(total questions - negative questions - closed - early deleted)/total questions >= 0.5
I can see only 9 questions under your belt now. So based on that questions you should get this badge. However as you can see in the given answer, you may have some closed/deleted questions which are older than 60 days in your history, which may be preventing this.
So You are not alone, lot of awesome-heart people suffer the same. Best of luck.
PS: May be moderators can give you more details regarding the calculation.
