Hide messages on next button

Awesome plugin-in it worked well so far for me, im just having problems with the next button that shows a message of “your info its been sent correctly” in every single step. I tried empty the message fields and the message disappear but the lines that border the message still showing. In the video tutorial when it hits the next button it does not shows any message. thats what i want.
