not displaying transposed/concert pitch accidentals correctly

I have imported from Finale a project for orchestra where the horns in F for some reason in without the corresponding key accidentals, both in concert and transposed view. But pitches are displayed correctly in both modes. Workaround is to change instrument, but is there a setting i have missed? in Layout options the transpose box is checked.

You are right : the method is to change instrument so that it matches the behavior you’re looking for. It’s as easy as going into Setup mode, open the players card and click on the > next to the instrument name and Change instrument… Choose the right version and that’s it. No need for any redundant option, I guess, but again, I 'm just a user. If there’s something missing in that workflow, feel free to develop here :wink:
