BUG: Split channel changes 5.1 to stereo

Can anyone replicate this in 10.2? I was doing an 5.1 export with split channels and it resulted in audio just on the L-R channels, all 6 channels got exported but there was silence on 4 of them. Switching to integrated changed the sound back to all 6 channels.

I opened the same project in Nuendo 8 and everything was normal there.
