Whether he requested the 'correct' spelling or not is unknown because we don't have Crowley's reply to Harris' letter dated 11th May 1941.

Correction: I should have said that IF he requested the correct spelling, such a request was obviously ignored. Judging from the way he micromanaged the project, I suspect that he never requested the spelling be changed.
Is there a reason for this? Perhaps. Spelling Abracadabra with a Chet instead of a Heh would result in a value of 421 instead of 418, and may relate to Hadit equaling 421, as noted in the old comment:
"AL I,16: "For he is ever a sun, and she a moon. But to him is the winged secret flame, and to her the stooping starlight."
The Old Comment
15. In II, 16, we find that HAD is to be taken as 11 (see II, 16, comment). Then Hadit = 421, Nuit = 466.
421 - 3 (the moon) = 418
466 + 200 (sun) = 666
These are the two great numbers of the Qabalistic system that enabled me to interpret the signs leading to this revelation.The winged secret flame is Hadit; the stooping starlight is Nuit; these are their true natures, and their functions in the supreme ritual referred to above."
Thus if we include the Moon (ruler of Cancer) as Gimel = 3 to the card of Cancer/Chariot/Chet/Abrahadabra/418, we get 421 = Abracadabra = Hadit
