Widget support Webilop User Language Switch

I was installed plugin ‘User Language Switch’ developed by Webilop and configure with 2 language English and Chinese. For the Post and Menu, it can handle language switching.

But when try to configure on widgets, such as ‘Text’, ‘Google Calendar’ under menu item ‘Appearance’—> ‘Widgets’. It can show section ‘Main Sidebar’ and ‘Main Sidebar / Chinese (Taiwan)’ and I can successfully add some simple Widget such as ‘Text’ into section ‘Main Sidebar / Chinese (Taiwan)’. And also even I try to use menu item ‘Appearance’ —> ‘customise’, the interactive editor can show Chinese text under Widget ‘Text’ and ‘Google Calendar’.

But when apply and saved captioned changes to my site (in production). I try to click the user language switch like national flag, it can direct to Chinese Post information but the the main side widget, such as ‘Text’ and ‘Google Calendar’ still show English, instead of Chinese.

Please advise what actions need to configure.

Thanks.
