SoapUI 5.2.1-REST Service's JSON response not displayed in JSON view

Hi,

When I execute REST service in Soap UI 5.2.1 Open source, the respective JSON response is not displayed in JSON view and instead below message is displayed.

"The content you are trying to view cannot be viewed as JSON".

Please suggest me if I have to change SoapUI settings to see JSON response in JOSON view

Please find below other views that I see.

XML View:

<data contentType="text/plain;charset=ISO-8859-1" contentLength="140"><![CDATA[{"status":{"resultCod​e":0,"developerMessage":"Hint question retrived successfully [Time Taken: 1103 millisec]"},"data":{"hintQuestion":"7"}}]]></data>

HTML View:

{"status":{"resultCode":0,"developerMessage":"Hint question retrived successfully [Time Taken: 1103 millisec]"},"data":{"hintQuestion":"7"}}

Raw view:
