Set Angle to 0; that's what's creating the twist. You probably want either Radial or Zoom, and just change the Length control. Choose the center point of the blur with the Center widget.
Centered blurs in both directions along the Angle, while linear toward the chosen vector. The Center blur will look identical whether the Length value is positive or negative, but in Linear mode, positive and negative blurs will look different—they smear in opposite directions.
