What you mean by cold and hot pulls?
The problem occurs during the print at a certain height.

That could be because the humidity in the filament causes it to clog a bit during its heating cycles.
However, check this out to introduce yourself to the hot and cold pulls to clean out the PVA.
When dealing with PVA, moisture in the filament is just the first go to response in almost every situation. Cleaning out the nozzle will rule this out.
The under extrusions happens to PLA, the PVA layers are all fine.
Doing a single extruder print with PLA directly after the fail print there is no problem with a clogged PLA nozzle.
Hmmmm, I missed that......I was looking at the wrong thing.....my mistake.
So, to make sure the wee brain is working properly, the PLA is fine on its own and under-extrudes when using PVA?

Exactly!
That is weird. I do not believe I have ever heard of that. I know I have never seen it on my printer.
Wanna try something out of the ordinary? Try switching the cores to the opposite slots and feed the materials through again to match the cores. Then, reslice so that the printer can identify which core is where properly, and see if it does it again.
I know it sounds weird, but maybe give it a try.

Have you done a series of cold and hot pulls to make sure the nozzle is not clogged. If the PVA gets too moist, and it does not take much for that to happen, it will clog the nozzle and prevent proper flow.
