Nevermind.
I got it working how it should.
Instead of the keypad button turning them fully on/off, I made the on button start lowering, and the off button start raising. Then a double tap on or a double tap off is set to the stop raising/lowering command. I tried that before, but since the on button was setting it to 100% and the off to 0%, the double tap wasn't doing anything.
Now it works well.
Thanks again.
