I add two tags of "ＧＤＰ" and "GDP" for Map object but Map.tagged_with ("GDP") return empty

I am so sorry for my first issue, please forgive me. Now i translate it in to english, and hope you can understand it .

I add two labels of ＧＤＰ and GDP, but I use Map.tagged_with ("GDP") or Map.tagged_with ("GDP") statement to retrieve the result and the result is empty. These two labels are full-width and half-width output.

How to resolve it ?
