Reply to jog wheel problem, always activated, PLEASE HELP, Video Included

For a quick look at the problem, check out this video I just uploaded to YouTube

When the metal plates are installed on the jog wheels of the VCI-100 they are always activated (red) as if they are being triggered by my touch. When the metal plates are removed the jog wheel performs normally as long as I am touch the screws to trigger the sensor. My understanding is that the screws are the metal trigger and when you install the metal plate it turns the plate into one giant trigger by creating a connection with the metal plate and the metal screws. What I don't understand is why whenever I install the metal plates the light turns red and the jog wheel is activated, even when I'm not touching it. Does anybody know what's going on and/or how to fix this?
