Missing temperature data in VDBs

[Rustmonkey]

Hello All, I'm newish to Phoenix, but pretty familiar with fire/fluid sim software. I'm trying to export a VDB for rendering in another renderer (RS). The problem is the temperature channel seems to empty. As I'm running the sim in Phoenix the fire looks correct and the appropriate export channels are on, and the resulting VDB has a temperature channel, it just renders a box. For the record though, the smoke channel seems to fine.
I know that when using Fumefx this way, the temperature channel in the emission slot of the volume shader is where I get my flames from, but this doesn't seem to work here (I tried the fuel channel as well, but got nothing)
I would truly appreciate any insight anyone might have.
Thanks!

Yes, I've seen this and this is my process but still no data in the temperature channel (but works in the smoke channel) so I think there is something missing in the VDB export
