QTI Line Follower question

I am trying to use the QTI Line follower with the cyber:bot. I have everything wired, and it appears to work to an extent. The video on the tutorial shows the lights to be off on the micro:bit until it recognizes a line. I have the opposite result. My lights are all on until it recognizes a line and then they turn off. https://learn.parallax.com/tutorials/qti-line-follower-cyberbot/testing-your-cyberbot-qtis
Why is this happening?

    Just noticed that 2 replies here from Ken and myself disappeared over the weekend.

    What's up with that?

    A-hah... our comments remain in the dual post in microcontrollers.
