Bot duplicates user messages when I use DirectLine channel - asp.net-core

Question

I am using bot framework v4. I have developed a chatbot using .Net Core. The bot is integrated with LUIS and Qna Maker. One issue I am facing is that the bot duplicates the message that comes from the user. Please look at the screenshot below:
The replies I get from the bot are perfectly fine. The flow of the bot is as intended. I just cannot figure out why the message from user is being duplicated. I am using DirectLine for this. I will share whatever code part is needed.
