Odd accidental behavior on basic key signature

I’m writing a very standard 3-horn chart for a jazz vocalist. The arrangement is in Ab.

Why on earth is Dorico choosing these as my accidentals in Ab? It’s becoming a bit counter-productive to keep having to change these very basic enharmonic spellings. The # notes should obviously be flat, so why is Dorico doing this? (And yes, the transposed score also does this odd behavior as well.)

Without seeing the project itself, I’m not sure I can offer any intelligent suggestions. I assume you’re inputting the music via MIDI keyboard.
