Chord Symbol Playback & Concert Pitch

Hello,

I was recently working on a transcription using Musescore 4 and I noticed that the chord symbol playback didn't work as I expected. I was writing a melody on Bb Trumpet and then added chord symbols above that melody. The problem is that the chord symbols during playback sounded in concert pitch, when they should've been playing back in Bb (My first chord in Bb is a Dmaj7, but it is sounding an EMaj7). The concert pitch toggle does change the chords but the melody shifts also, meaning we are stuck with chords that don't fit the melody.
I hope I could help!
