Buzzb, I'm having the same problem, though I don't think the first letter of the initial entry for 34 has to go in the unchecked cell for 32. I assume the answer to 32 is adjectival, so ends in Y, and the Y must go in the unchecked cell for 32, making a real word in the final grid.
However, that conflicts with my conclusion reached a while ago that the the letters in the unchecked cells of across entries were in the same positions as the clued answers, so, for instance, the unchecked letters of the entries for 6a and 44 are the same as the final entries.
In 32a that does not appear to be the case.
