3d Widget slider - VR Interaction Lock On

I currently have a 3d UMG slider widget working properly that I placed into a level. I simply use the HTC Vive controller with the Widget Interaction’s debug tracing on and drag the slider as usual.

The problem I currently have is that the slider is a little larger/longer than usual, and sometimes as I’m sliding it across, my controller’s interaction with it “misses” the slider unless I physically and accurately slide it.

Is there a way to change it so that as soon as I interact with the slider, I can just freely move my controller left/right to slide it across without having to worry about precision? I tried to cheat it a bit and make the slider nub larger than usual but it doesn’t seem like an effective workaround.
