Hi Thank you for the reply.I went and changed the language from user reference but its only changing the value when i hover on that not the value showing on aem instance. Can you please help me on this. 

I am facing issue, where in AEM instance search, solution and help options are coming in Portuguese. I want to know the root from where its coming and how can i change the language to English. Adding the screenshot for reference.
