drone brood in super help....

It’s got the chair of the association baffled though

If you become a chair of a BKA has usually absolutely nothing to do with your competence as a beekeeper.

It's also possible that the queen is slimming down a bit (in spite of still laying well) and squeezing through the QE. Maybe it's because the brood box is too crowded? Or the QE is becoming distorted. Is it one of those plastic QE's with slots? I've had failures with those.

I had wired queen excluders that didn't stop the queen and ended up with patches of worker brood in supers on three hives. I checked the excluders carefully and couldn't find any defect. I've gone back to moulded plastic excluders this year.
