I had this problem with canola stalks and could not get it sorted. I ended up pulling the middle seive out and making an extension for the top chaffer so that it ran full length - I made this out of the unbroken section of the old top chaffer seive. This worked good in canola and I changed back to the three step setup for wheat and barley. Its not hard to do if you have that old seive section.
