I had an EFB scare a few weeks ago. I called the SBI in my area, who came out sharpish with a test kit and acknowledged it looked odd. Apparently in the early stages, there're a few things that can have similar effects on the larvae i(n that they starve in their cells). I can't tell from your picture, but poss chalkbrood in top right, and something in bottom left. Can't see other cells clearly enough, though see what you mean about larvae in strange position.
Have you had any other snags with the colony that may have induced any stresses?
I would definitely echo advice to call the inspector. My mind was put at rest and I had a sensible way forward, which appears to be working so far (after a few weeks).
Good luck.
