Polyline Tool Offcenter

I am using the polyline tool for a turn around, and I am having a bizarre problem. When I use the polyline tool, the actual stroke is above where the points are. I will draw a shape using the polyline tool on one spot, but when the line appears, it is about a cm above the intended spot. What’s even stranger is, the further I go up towards the top of the scene, the further away the stroke gets from the path. Does anyone have any idea what is wrong? I have tried restarting Harmony, and erasing all keyframes. I’m quite stumped.
