which is why I set out the issue I had experienced
Are you aware of the size of 10-15mm? Are you sure you were not visualising 10-15cm?
Even a lot of the inexperienced beeks will know how much drone comb is built below the frame bottom bars in a Standard bottom bee space set-up, let alone with half that, or even less than that.
I would suggest either checking on a ruler or changing your bees.
