I can duplicate your problem like so...
I create an Adobe Dem project file, bake, and in a smart mat for Wood Ship Haul Old.

Then when I change the shader to PBR Metal Rough and add in any material it turns green.

If I toggle off the emiss from the fill layer or turn it off in the settings here:

No more green... This also happens if you have fill layers prior to going to PBR Metal Rough as those prior channels had Emissive by default.
I found it occurs by the emissive channel within a layer, fill layer, or material.
Try turning it to 0 so it's globally changed and then you'll know if that is your problem, as opposed to going to every layer and toggling it off. You can also remove Emissive from Texture Set Settings under Channels.
