Release All releases which support Service Portal

Cause The Language picker was rendered via the "Knowledge Language Picker" widget on the affected instance. On this widget, there was a server code to add English as below,

var recordEn = {}; recordEn.label = "English"; recordEn.value = "en"; languages.push(recordEn); This custom code was causing the duplication.

Resolution Revert the "Knowledge Language Picker" widget to the OOB version, this should resolve the issue.
