Render Passes issue in 4.26.0?

Hi,

So i’ve set up a fairly basic sequencer to test features out:

  • Bunch of individual sequence shots, just with a camera move and camera cut inside
  • a level sequence with these all together

I output to an EXR sequence fine which is great - i get all shots, correct cameras.But upon switching to Render Passes the result is i get the same static camera for each image - though sometimes i get a random frame of the correct camera mixed in. What is odd too is that the live preview that pops up as it saves looks correct - as in it plays through the shots / cameras correctly. But the result on disk doesnt match

Is there any details that might cause this? maybe a way of putting together the sequence that render passes dont like?
