Comment on Odd wiring in a 2-gang

It's a little hard to imagine without a diagram like the other poster mentioned. But what might be happening is that the 'travellers' (What you were calling the two neutrals) feeding each switch may have been mixed up. Try swapping two of them, or if you're confident using a meter check that the two travellers for each switch are attached to the corresponding switch on the other side

Ok, so travelers in a virtual 3 way are non-existant really. They are repurposed as the load wire in a single-way. Basically: virtual 3-way eliminates the 3-way setup, instead having the 2nd switch simply communicate that it was pressed to the main smart switch. If you peek at the link I posted in OP, you can see a diagram of the wiring (obviously in the correct state).
I am confident with a multimeter, are you recommending a continuity test? I could tie the load & traveler together, unless there is some other way to test which traveler corresponds to which main switch?

It's been a few years since I worked in the field so the virtual three-way is a little bit more advanced than I'm used to. But yes I was suggesting a continuity test. One way to do it is that if the boxes are grounded you can test continuity to ground by touching the wire to the box on one side, and then using a meter check to see which wire has continuity to ground on the other side. Power off both circuits before grounding any conductors

figured I would respond, but your advice was good! got me to find a known good and work from there. posted an update to the OP.
