What to do: regulator runs out of travel before fully up

[Jemo]

I'm doing the Black Diesel vent window delete mod (which has been Great!) and now have everything finished and trying to adjust the regulator. The window rolls down fine with no issues but when I roll the window up, the window stops about 1" from the top. The regulator is out of travel but I can gently push the scissor arms up and the window goes right where it needs to be. I'm guessing the regulator is out of travel because the splines don't move at all when I push the window up. Is there something on the regulator arm that needs to be tightened or do I have bad regulators?

Thanks,
Jeff
