2025 Tahoe RST still flashing blue with amber TA engaged

Was recently assigned a 2025 Tahoe with slicktop package. When in park with the amber Traffic Advisor engaged, the blue lights are still flashing as well making the TA not effective. This is only in park. I've spend a couple hours on the program and simulate trying to figure out what the upfitter did, but cant isolate it other than something with the park sensor setup. Any ideas or anyone willing to take a look at the config?
 
If your using Core, sounds like you need to make an “Event” in the Command software

or

When using traffic advisor, be sure to “Turn Off” the blue in Command if you bar is a duo color LED.

That’s all I can think of off the top of my head without looking at the program.

Whatever input you are using to turn on your TA, also needs to turn off the other colors flashing. In addition to that, that input needs to be set higher in priorities than the input that is turning on your flashing lights. When i set up a program in command, Takedown and Alleys usually have highest priority, followed by TA functions. Im assuming that your problem here is that there is an event for a different pattern in park. One of the conditions in that event has a higher priority than your TA input.
