Why does my character never land?

Attached is an image of the Debug text showing which methods are being called in this constant state of falling. Once the character steps onto this hexagon which is at a perfect 90 degrees in the world they enter the Compute slide vector/ sliding phase, they also appear to be falling. Because I have air control enabled I can dictate which direction I slide on this surface. If I were to fudge the controls just a little so that the character no longer slides and stay perfectly still, then only the Physfalling Method is being called
