Musescore 4: Chord symbols not sounding in the right key.

Hi all! I just downloaded Musescore 4: the problem that I am about to describe doesn't occur in Musescore 3.6.

When I create a new score from scratch, the chord symbols don't sound in the same key as the associated notes. For example, if I have the notes Bb D F A, and I apply a Bbt7 (Bb major 7) chord symbol, the chord symbol does not play in the same key as the notes (I'm writing for alto sax, which is in Eb). I'm assuming that the chord symbols are probably in concert pitch, but I can't find any setting to change them to be keyed for an Eb instrument. I never had to change any such setting in Musescore 3.6.

When I write a new piece in Musecore 3.6, this problem doesn't happen. This same problem has been reported by at least one of my colleagues as well. Any help would be greatly appreciated. Thank you!!!
