Then it will probably be as Andgle said, an override in Engrave mode on the Accidental setting.
I find it hard to see the difference between slurs and ties on first view sometimes, but I did some experimenting and slurs do connect a bit higher/lower along the stem.
„in Engrave mode“ was the clue. Yes, in Engrave mode one can modify the accidental of the second note of the tie. It does not work in Write mode (even as the switches are present).
Thank you… it took some time… now everything is fine
the funny thing is that there is no setting in Dorico to repeat accidentals on tied notes (which is rather common in french editions e.g. as was discussed in another thread long ago), so if this was entered in Dorico you wouldn’t be getting an accidental on the top Eb either. If this accidental was somehow frozen in the XML source, Dorico would show it, but then ‘Reset Appearance’ should really have removed it…
fratveno, I do have another problem with this file (Rehearsal marks in flow 1 would crash Dorico).
So I am just waiting a few days until version 1.1 will fix this
