Data getting removed from Q&A bot.

Hi i deployed the existing q&A bot by aws (https://github.com/aws-solutions/qnabot-on-aws) and while testing the content design . I am adding questions to bot but they are not coming in the bot It still answering blank and when i refresh the page all my added questions are removed. Added questions are also not coming in the test exported file. Is it like this only or am doing something wrong
