Air walls getting erroneously assigned to internal ceilings?

Hello All, back again with what I hope is a simple question, but I have not been able to find a similar thread in this forum.

I am trying to assign certain internal walls as AIR WALL, but I'm running into two problems:

1) The SolveAdj component is assigning the internal ceilings as AIR WALL too, which I don't want; and

2) I can't figure out how to assign only some internal walls as AIR WALL.

I only want the walls between conditioned zones to be AIR WALL. I separated out my conditioned and unconditioned spaces and tried a two-step SolveAdjacency process, but then it thinks some internal walls are external walls, which I also don't want. I tried using the setEPZoneIntCnstr component, but when I label surfaces from it, it doesn't appear to have changed anything. I also just can't figure out how to select only adjacent conditioned surfaces to change.

I have attached my GH file with notes about what is happening when. Would appreciate any assistance on this! Thank you!!

I will admit that I am just a beginner, but, I would look into creating more detailed zones from surfaces as in Chris Mackey's youtube videos. With that work-flow you can just intersect/split the shared surfaces and manually assign their properties.
