Mass disenchant still showing lesser dust value

Before patch 24.6 I had my mass disenchant dust value around 100k dust, now it’s 83k. I thought the reason of it was KoFT moving to standard\core, but no changes today after release of MotLK.
Several other people had the same issue, no response whatsoever - Mass disenchant showing a different dust value

Can you confirm it’s just a visual bug or resolve it? This is quite major in real-money costs, you know.
