All apps not recognizing Slide

I just received my Ink and Slide!

However, none of the apps recognize the slide. It appears the sensor on the end away from the button is not working. I noticed this because my pinky slipped off of that end and hit the screen and suddenly the lines appeared. I've also ensured the slide is not dirty.

The stylus is fine and works perfectly and the tips in here about turning on the palm rejection were great. Should I contact Adonit?
