Q Light Controller+

I need to use a GPIO on the Raspberry PI to turn off a switch when my show starts. I have compiled QLC from source on a Rasberry PI 4 Model B. I can enable GPIO in my universe and I am able to create a simple dimmer that is assigned to that GPIO number. This works fine in simple desk. I can move the slider all the way up and down and the GPIO switches fine. I created a scene using the fixture and added it to my show and the GPIO doesn't switch. I really need to get this working. I feel like I'm missing something simple but I don't know what it is.

In Simple Desk, make sure there are no red 'crosses'. Using Simple Desk overrides everything else.
2nd - Is there a 'monitor' to validate output somewhere? I'm not sure...
