Volume Pedal lowest value is 118...

I'm using a Yamaha volume pedal going to my VX8 on Pedal B. The default parameter of this is Expression, but even when I change it to volume in the controller, when it is fully back, the value in Main Stage is 118, and it doesn't start to tick forward till I'm 3/4 of the way up on it. There is no calibration setting on the pedal, and this same volume pedal works fine with my Triton Studio... I really use this pedal a lot when I'm playing organ, and this little problem could make things very inconvenient... Any ideas? I thought that this might be a controller issue since the controller is what sends the value, but I've got a UF 60, and I have the same exact problem with it...
