In the pull-down menu of languages, I see the following lines:
zh-simp - 简化中国 - Chinese (simplified) - jugbau
zh-trad - 中国传统 - Chinese (traditional) - jugbau
I think these Chinese characters show strange translation from "Chinese (simplified)" and "Chinese (traditional)"; moreover, the translation of "Chinese (traditional)" is shown in simplified characters. I recommend replacing them with the following lines:
zh-simp - 简体中文 - Chinese (simplified) - jugbau
zh-trad - 繁體中文 - Chinese (traditional) - jugbau
