ccp_autoDetectLanguage misbehaving when changing language 2 times

Hello
I face to the issue and I don't know how to fix it. Please give some help!
My app support 2 language English and Chinese. Normally, opening the app and the language is English, ccp's language is also English too. It's correct.
But when I change app's language is Chinese and change it back to English -> open ccp dropdown -> the language still is Chinese.

Start by reproducing the reported sequence in the Android library: begin in English, switch the app to Chinese, switch back to English, and open the CCP dropdown. Trace ccp_autoDetectLanguage during those changes; done means the dropdown uses English after returning to English.
